Purpose: 


The purpose of this science fair project is to demonstrate how a catalyst can be used to affect the speed of a chemical reaction.  A catalyst is a substance, solution, or variable that changes and increases the rate of a chemical reaction.  In other words, a catalyst speeds up a chemical reaction. 


Alka-seltzer tablets consist of citric acid (sour salt), sodium bicarbonate (baking soda), and aspirin. 


Hypothesis:  An increase in temperature will speed up the chemical reaction.  Therefore, the hot water will provide the quickest catalyst and dissolve the Alka-Seltzer table before the lukewarm and cold water environments. 




Variables:

  •  
  • Temperature of the water - hot, lukewarm, cold
  • Plain water in drinking glasses
  • Baking powder and water in the drinking glasses
  • Baking soda, sour salt, and water in the drinking glasses

Materials Needed:


  • Three Alka-Seltzer tablets
  • Baking powder
  • Baking soda (sodium bicarbonate)
  • Citric Acid (Sour salt)
  • Water
  • Three drinking glasses
  • Note cards
  • Tape
  • Marker
