Essay On Soda Water Titration

The topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of water used and the Alka Selter compound. The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds.

Our objective was to pick the best chemical to be used in a hand warm. This chemical had to be cheap, relatively safe, and must raise the temperature by 20oC and no more. We add 6 different chemicals to water we record the inshell temperature and then add one a the 6 chemicals to the water and record the temperature change of the water. We also add cold water hot water together to find how much heat would escape the calorimeter. We found that the calorimeter absorbed 71.1J/oC. Then this information to calculate the energy that was released by all of the chemical reaction. We found that Joules from NaCl = 340 J, NH4NO3 = 1340 J, CaCl2 = -2320 J, LiCl = -3600, Na2Cl3 = -720 J, NaC2H3O2= 1070 J. Then we used energy release from one one these rxn to calculate the Hor the KJ per mol rxn.

Alka-Seltzer is a medical drug that works as a pain reliever and an antacid. The pain reliever used is aspirin and the antacid used is baking soda. When sodium bicarbonate dissolves in water it splits apart into sodium and bicarbonate ions. The bicarbonates reacts with hydrogen ions from citric acid to form carbon dioxide gas and water. This is how the bubbles are made. How is temperature related to this reaction? The higher the temperature the slower they move.

The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield. Weighed 1 gram of NaC2H3O2 and mixed it with ionized water. Boiled 12 mL of 1.0M Acetic Acid added into a beaker containing the sodium carbonate on a hot plate until all the liquid is evaporated

I would like to thank the people who were involved in my project would be my mom and dad who are helping me by buying the materials i need for my project. They also helped me by testing it at home.

Pop Rocks and soda have a very interesting chemical reaction with each other. Soda is a

1. Suppose a household product label says it contains sodium hydrogen carbonate (sodium bicarbonate). Using your results from Data Table 1 as a guide, how would you test this material for the presence of sodium bicarbonate?

If greater and higher concentrations of cobalt chloride are added to each solution then greater amounts of light would be absorbed by each solution. Thus a liner relationship will result in which the absorbance of a substance would be proportional to its concentration, which will be depicted, in a linear graph.

Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment. In the second portion of this experiment we will keep the temperature constant and divide the ½ tablet of Alka- Seltzer into 2 pieces ,3 pieces and an unbroken ½ tablet. It is my belief that Alka-Seltzer

When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area

Soda can hurt you in many different ways. As it states in the 2 articles about sugary drinks. The 2 author names are Russ Floyd and Evan Cook. Russ Floyd kinda has a point in his article since they do affect you. But Evan Cook has a point to since it is your body. Plus, you can make your own decisions.

To calculate the concentration of ethanoic acid CH3COOH in vinegar using stoichiometric equations, ( Yamaha brand )

For this assessment we had to solve and answer problem by designing a fair and accurate experiment. Sodas and carbonated drinks are one of the many things we see in our life. Our group has looked into carbonated drinks and how they work. However, we did not know the answer to one question: Which soda is more carbonated?

Two sources of error may have affected the experiment. Firstly, the experiment required volumes of liquid to be recorded while the vapours were distilling. It was impossible to accurately measure the volume of liquid at any given moment, as the meniscus was moving side to side. Secondly, the distillation was ended while there was still liquid in to round bottom flask. The composition and volume of this liquid were unaccounted for in the calculated

Have you ever just wanted to have a soda at school? Have you ever been having a bad day at school and just want a nice cool, refreshing beverage, but then you realize… you’re at school? According to NY daily news “soda gets a bad rap for making us fat, rotting our teeth and even possibly making us depressed. But hey... it's not all bad news with the bubbly stuff.” A weird fact about soda is “soda is one of society’s favorite beverages. Each year, billions of gallons of soda are sold in the United States alone.” Soda must be allowed to middle schoolers during school hours. Soda should be allowed because kids need more of a choice at school and soda is not the cause of all the bad stuff.
