Chemical Reaction and Temperature Lab Investigation

Introduction:

The lab investigation we did was called the chemical reactions and temperature. The problem that we were trying to solve was how does temperature effect chemical reactions. Our hypothesis for this question was that the warmer the temperature, the more of a chemical reaction will take place because there will be more energy stored in the water the shorter the reaction will be. Our idea for this hypothesis came to our minds by how whenever there is ton of energy the faster something happens. The more signal you have for your phone the faster you can reach and search the Internet. Same thing with the water, the more energy there was in the water the faster the tablets dissolved.

Results:

Temperature When The Tablet Was Dropping In	How Long The Reaction Was Taking Place	Which Test Was Being Tested
2.8 °C	2 minutes and 30 seconds	Cold Water
22.2 °C	34 seconds	Room Temperature Water
50 °C	21 seconds	Hot Water

Here is a picture of what the setup of the beaker and the thermometer was before we dropped the tablets in.

This was the temperature throughout the Room Temperature Test! You can see it stayed the same throughout, because there wasn’t any new or old energy being formed or going away.

This was the temperature throughout the Hot Water Test! You can see that it kept rising until it reached 50°C then it started to go down from its’ climax of energy.

This was the temperature throughout the Cold Water Test! The temperature went down from room temp. then after the energy was gone it started to rise up again after the test.

Conclusion:

Our hypothesis was correct! The warmer the temperature, the more of a chemical reaction took place because there was more energy stored in the water so it made the reaction shorter and faster. The only difference between the test was how long it took for the tablet to dissolve. The outcome look of the dissolved tablet was just some fizzy stuff on the surface of the water. When the chemical reaction was taking place for the hot water, as soon as you placed inside it started to fizz and go crazy over all the energy inside the water! The reactants of the experiment were the tablets and the water. When we added the energy to the water by changing the temperature it made the product which was the mixture of the tablet water.

This lab was very interesting. At home I have this tablet call Airborne, which basically is a Vitamin-C supplement. And whenever I dissolve it, it is usually in cold water, so now I know room temperature or hot water makes that process go way faster!
