What happens when Alka Seltzer is mixed with Water?

Graph of Experiment

When Alka Seltzer and Water were mixed, the temperature decreased. This is an endothermic reaction because energy was absorbed. The lowest temperature was 30.5 degrees Celsius and the highest temperature was 30.9 degrees Celsius.

Breakdown of the Reaction

In this reaction, solid Alka Seltzer is mixed with Water. The Law of Conservation of Mass is demonstrated as follows:
