An Inquiry Into The Effect Of The Molarity Of Salt Water On The Boiling Point
Josie Krueger March 22, 2023 Title: An Inquiry into the Effect of the Molarity of Salt Water on the Boiling Point Word Count: 984 Overview: This lab was an inquiry into the relationship between the molarity of saltwater and its boiling point. Testing in this lab consisted of four separate molarities, along with three trials per molarity. The lab modeled a form of chemical reaction called ionic bonds, and highlighted common chemical reactions in life. Testable Question: How does the molarity of saltwater (M) affect the boiling point (C°)? Background information: In order for water to boil, a large amount of energy must be involved. In fact, in order to raise the temperature of one gram of water by one degree, one calorie of energy …show more content…
This is due to the fact that the ionic forces brought by sodium (+) and chlorine (-) result in stronger intermolecular bonds. Chemical bonds called ionic forces are formed in saltwater solutions and have a greater degree of polarity than hydrogen bonds. As a result, the boiling point rises (Ashenhurst). Hypothesis: If the molarity of saltwater is increased, then the boiling point will increase because the strong intermolecular forces called ionic bonds formed in a saline solution prevent water from evaporating as efficiently. Variables: Independent Variable Modifying the molarity of the saline solution …show more content…
The beaker was placed on the heating element on high heat and was left undisturbed until it began to boil. When the solution reached a rolling boil, the temperature of the water was tested and recorded utilising the same method as the first trial. Two more trials of the 0.5 M mixture were conducted. The experiment was repeated three times more with 11.688 grams of salt to create a 1 M mixture. The experiment was repeated three times more with 17.532 grams of salt to create a 1.5 M mixture. The experiment was repeated three times more with 23.376 grams of salt to create a 2 M mixture. The materials were cleaned up and the beaker was

1454 Words | 6 PagesA hot plate was placed under the ring stand. 50 mL of 3.0 M NaOH in a 250 mL beaker and a stir bar was placed in the beaker. The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved.

1232 Words | 5 PagesAfter the water temperature began to stabilize, the highest constant temperature was recorded. This data was used to calculate the calorimeter constant. This enter procedure was repeated to calculate another calorimeter constant in order to find the average of both answers. After that value was calculated, a 600 mL beaker was filled with 300 mL of water and heated till it started boiling. An unknown metal located on the instructor's bench was obtained and the mass was calculated.
Summary: Crush The Can Experiment Write-Up
355 Words | 2 PagesThe science behind this is very simple, it involves the behavior of gases. Atoms in a gas is free flowing. They respond and move faster when there is heat, and slower when it is cooler because of a loss of energy. It then changes the pressure of the gas, as the atoms in a certain volume of gas changes. In this experiment, we heated to can with water in it until it was boiling, which
Boiling Point In Intermolecular Science
1053 Words | 5 PagesA boiling point of a substance is dependent on the temperature at which the substance can change its matter, such as liquid to gas. The molecules present in liquid are tightly compressed together, though they are still moving and colliding. If the liquid is heated, there is a rise in temperature which generates vibrations throughout the liquid, resulting in more collisions between molecules (Helmenstine, 2017). Once the collisions between the molecules become quite intense and rapid, boiling starts to take place. There are molecules that are so powerful, they break through the attraction forces that keep the molecules together, this is called intermolecular forces (Ophardt, 2013).

2474 Words | 10 PagesA liquid will boil at the same temperature, and many different liquids have boiling points that are much different from one another. This fact can be used not only to distinguish/identify liquids, but also to separate liquids in a mixture. Though boiling point is constant according to substance, boiling point and air pressure vary directly. This means that boiling point is lower at high altitudes than at sea

621 Words | 3 PagesThen the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap

976 Words | 4 PagesTrial #2 and Trial #3 were used to determine the freezing point of an aqueous solution. The “Unknown C” was used to create the aqueous solution. For Trial #2, 2.0019 grams of “Unknown C” were weighed and dissolved into the 11 dram vial. Once dissolved, the 11 dram vial was submerged into the ice bath, and the Vernier temperature probe was immersed into the 11 dram vial as well. Once the temperature of the aqueous solution reached 10°C, the temperature was recorded every 10 seconds.

1027 Words | 5 PagesEach buffer was measured in a 100 mL graduated cylinder and contained in a 40 mL beaker. Once the reading of the buffer was stabilized, the program entered into reading 1. The probe was cleaned with distilled water and dried before being placed into the second buffer for reading 2. Once the second calibration was completed the pH probe was cleaned again. Next the probe was placed into the unknown solution.
Why Did Salt Stay Used In Food Processes?
898 Words | 4 PagesSalt: 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.

How Does The Concentration Of Water Affect The Preparation Of Nacl Rates
1864 Words | 8 PagesThe boiling point of the solution will be higher than that of the pure solvent itself. The boiling point of a liquid is the temperature at which its vapor pressure is to equal the atmospheric pressure. When a solute is added there are less solvent molecules near the surface and the solvent’s vapor pressure will decrease, so the vapor pressure of the solution will be less than that of the solvent. For the vapor pressure to reach the atmospheric pressure, a higher temperature must be reached, which means the boiling point is elevated. According to this theory, adding salt to water would make the boiling point higher, and make it harder to reach the boiling point.

446 Words | 2 PagesDiscussion: The mass of the lye was taken twice, and the mass of half a teaspoon of lye is 3.3 grams, as 1 teaspoon of lye was 6.6 grams. The initial temperature of the vinegar was 16.0° C. For the first trial, the final temperature was 31.0°C, meaning the ∆T was 15.0°C. The final temperature for the second trial was 33.5°C, which indicates that the ∆T was 17.5°C.
Water Hydration Lab Report
603 Words | 3 PagesIn this experiment, the amount of water lost in the 0.99 gram sample of hydrated salt was 0.35 grams, meaning that 35.4% of the salt’s mass was water. The unknown salt’s percent water is closest to that of Copper (II) Sulfate Pentahydrate, or CuSO4 ⋅ 5H2O. The percent error from the accepted percent water in CuSO4 ⋅ 5H2O is 1.67%, since the calculated value came out to be 0.6 less than the accepted value of 36.0%.This lab may have had some issues or sources of error, including the possibility of insufficient heating, meaning that some water may not have evaporated, that the scale was uncalibrated, or that the evaporating dish was still hot while being measured. This would have resulted in convection currents pushing up on the plate and making it seem lighter by lifting it up
