Abstract
The purpose of this project is to see if the scientist can measure the effect of temperature on the rate of a chemical reaction by using Alka-Seltzer tablets and different temperatures of water. It is hypothesized that the Alka-Seltzer tablet will dissolve the fastest in the Hot Tap Water because of the higher temperature.

The Effect of Temperature on a Chemical Reaction?

The purpose of this experiment is to determine if the scientist can conclude in which temperature of water an Alka-Seltzer tablet has the fastest reaction time. The scientist will measure the time of reaction in temperature of water several times to come to an accurate conclusion. “With an Alka-Seltzer tablet, the CO2 is produced as result of a chemical reaction” (Spangler, 2010). The chemical reaction that occurs when the tablet interacts with a substance is known as effervescence. This process produces immediately creates bubbles or “fizzes” and is the product of baking soda (sodium bicarbonate) and citric acid reacting to form sodium citrate and carbon dioxide gas; which is the main reaction that is known by alka-seltzer tablets. (Chemistry of Effervescence, 2008). Hypothesis

It is hypothesized that the Alka-Seltzer tablet will have the greatest reaction time, then it will be in the Hot Tap Water, then the average time will be faster than that of the Cold Tap Water and Ice Cold Water.

Procedure
Using a measuring cup add eight ounces of water to a glass, mark with a strip of masking tape so that the water will be at the same level each time; pour out the water. Next, add eight ounces of HOT tap water to the level of the masking tape. Measure the temperature of the water, record it, remove the thermometer. While the helper holds the stopwatch, drop the Alka-Seltzer tablet into the water. Stir the water gently with the chopstick until the tablet has...
