Khewra Salt Mines Essays

My hypothesis for this experiment was not what I expected it to be. Instead of having each section grow in size due to the solution was incorrect. I only had my 1% with solution grow. This is the lowest concentration level I had and my lowest number of brine shrimp in the section without concentration as well. The other sections with my 5% and my 10% concentration ended up with no hatched eggs at all. This could be due to enviornmental reasons. Due to the enviornment brine shrimp usually have

This experiment was not carried out in chronological order to maximize efficiency. First the volume (3.33mL) of needed liquid ammonium sulfate was calculated based on the assigned 25% saturation. 3.33mL of the liquid ammonium sulfate was added to 10mL of the protein extract (given by the instructor) in a centrifuge tube to precipitate the protein out. Water was then added to a second centrifuge tube to balance out the mass in the centrifuge. The mass of the mixture was weighed and the water was measured

During the experiment, .002 Molar (M) iron chloride (4 mL), FIT (~10 mg), and ascorbic acid (~.66 mg) were used. Samples were prepared using the iron chloride (.002 M) and diluting it with distilled water in a clean, dry test tube. To prepare a solution, one milliliter of iron chloride was measured in a graduated cylinder and placed into a test tube. Distilled water was added to the test tube using a measuring pipette. Amounts of distilled water added varied based on the desired molarity of the

The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder

above the mean percentage of water in the iron salt crystal was 6.27%. The mean percentage of the potassium ion was determined to be 17.81%. For the iron ion the mean percentage was 12.20% and the average percent for oxalate was 57.20%. The total percentage of the mean adds up to 97.28%. The empirical formula using the means provided created the formula K2Fe(C2O4)3*2H2O. The total molar mass in this equations is 434.05 grams. The percent yield of iron salt using the actual yield of 8.71 grams with a

Objective In this experiment, the critical micelle concentration of sodium dodecyl sulfate (SDS) is determined by the conductance method. Procedure In this experiment, a series of SDS solutions at various concentrations are tested for their conductance at two different temperatures, 25 °C and 50 °C. For detailed procedure, refer to the lab manual (J. F. Wójcik and T. S. Ahmadi, Experimental Physical Chemistry, 2015; p.125-129.). Data Sodium dodecyl sulfate has a molecular weight of 288.372

Salt: Q1: What is salt? Salt, otherwise referred to as sodium chloride, is an exceedingly common mineral that is known for its strong flavour and crystalline appearance. Because of this, salt is routinely used in the preparation, preservation, and seasoning of foods the globe over (though the latter purpose is by far the one most commonly utilised), as it has been for generations. Q2: How was salt traditionally used in food preparations? Throughout the large majority of human history, salt has been

Salt does dissolve in water. But, there is a maximum limit of concentration that salt can have. When the salt concentration reaches its limit, the salty water has become saturated, meaning that the salt content in the water is so concentrated, there is not enough water left to dissolve the rest of the salt. And this would be the only time salt would not dissolve in water. When salt goes into water, the water will cause the sodium and chloride atoms from the salt to pull away and make the salt crystals

Procedures 1.First thing needed is a plastic bag open the plastic bag and take about a teaspoon of calcium chloride, put the calcium chloride in one corner of the bag. Then take about a half teaspoon of sodium bicarbonate and put it in the opposite corner of the bag. Then lay the bag flat on the table use about 5 mL of phenol red. Once the phenol red is in quickly lift your bag and put all the substances in one corner. Then observe 2.Reference procedure one for first step.Lay bag down and add about

1- 800 mL of raw water was transferred to six beakers using a measuring cylinder and a marker was used to assign different numbers to each beaker. 2- To make sure the pH was varied during the first part of the experiment, the pH in each beaker was adjusted. Using Hydrochloric Acid and Sodium Hydroxide, the pH of the six beakers was adjusted as follows: pH 3, pH 4, pH 5, pH 6, pH 7, and pH 8. However, the pH does not need to be exact. 3- Next, add 3 mL of Ferric Chloride coagulant using cylinder

Why was Salt so Valuable in Ancient times? By Lucas Oberg You want to know why salt was so valuable in ancient times? You have come to the right place. Salt was so valuable in ancient times because sometimes people were paid with salt. Also it was hard to find, People also traded salt for gold. Salt also has a lot of different roles. It could also preserve food. This is some of the reason why salt was so valuable. Why was salt so valuable in ancient times? You might ask this. The main reason

(1) The purpose of the separation lab procedure was to help my group members and I successfully formulate our own plan before completing the experiment, handling multiple materials and substances, etc. It acted as a step-by-step plan that guided us throughout the experiment and ensured that we were well prepared ahead of time (ie. knowing what kind of materials were necessary and gathering the correct measurements of each substance); this made the experiment day much less hectic for all of us. It

Salt- A history Mark Kurlansky was born in Hartford, Connecticut and attended Butler University. Receiving a BA in Theater in 1970, Kurlansky worked in New York as a playwright, ultimately leading him to writing his first book, “cod: A Biography of the Fish That Changed the World”, which quickly became a new york times bestseller, and it would not be his last. The book that this essay is about is Salt: A World History, is exactly as the name implies

Introduction and Historic Background Sodium chloride is also known as salt. The molecular formula for sodium chloride is NaCl. NaCl has a molar mass of 58.443 grams. Sir Humphry Davy discovered sodium chloride in 1807. He was able to extract sodium from its compounds, which included sodium’s connection with chlorine. Sodium does not appear by itself naturally, so it was important that Sir Humphry Davy figured out how to get sodium by itself. The salinity in the ocean is in large part to sodium chloride

BAKING POWDER, WASHING SODA Objective: To understand the use of common salt (NaCl) for preparation of chemicals such as Sodium hydroxide, Bleaching powder, Baking powder, Washing soda. The common salt (Chemical formula-NaCl, Chemical name- Sodium chloride) that we eat in our daily diet is the raw material for preparation of chemical compounds such as Sodium hydroxide, Bleaching powder, Baking powder, Washing soda. NaCl is a neutral salt. Sodium hydroxide (NaOH) also known as caustic soda is formed when

Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic. Blubber is a thick layer of fat that helps prevent sea mammals from getting too cold. Blubber in depth, is an extra digested food stored in the form of adipose tissue, which contains molecules called

families in the Bay, moving away, finding another means of survival, or abandoning traditional ways is simply not an option. The community is so immersed in generational traditions that to remove it would be a catastrophic detriment. This Pebble Mine operation if completed will be one of the most devastating violations of environmental justice that the

The Living Situation Affects Carrie’s Moral Judgments In Theodore Dreiser’s Sister Carrie, Carrie Meeber, a young provincial girl without money, social status, and special ability, comes to glamorous Chicago alone. In such a poor condition, if she wants to chase her dream to live a high-level life in the urban, she must suit “the discipline of society” and it is like “the law of the jungle”. The city processes the cruel survival competition. Thus, she has to face two choices: “Either she falls

Lost Innocence is a major theme throughout in all three novels. Each novel portrayed it in different ways and each novels is also has a variety of other minor themes. When Liesel moves to Himmel street she befriends a young boy named Rudy. Throughout The Book Thief Rudy symbolises pure innocence. He never understands what is going on around him. He is know as the boy who is obsessed with the black athlete Jesse Owens. One day he paints himself with charcoal and runs around a field. His father catches

World War I was one of the very first wars that had a global effect on the whole world. According to the book about WWI, The Guns of August, A shocking 32 countries took part in it. In the very first stages of WWI, the U.S stayed neutral, and had good reasons for doing so, too. However, the U.S eventually became entangled in the conflict anyway. Three leading causes forced the U.S to join WWI. The first reason was the sinking of the ship Lusitania. The second conflict was the sending of the Zimmerman
