Innovating Science Autocatalysis Demonstration Kit

Catalysis is a basic principle of chemistry and biochemistry. Some reactions are autocatylic; the product of the reaction actually catalyzes further reactions. The reaction is initiated with acid and produces acid to continue the reaction. In this activity, a Toluidine Blue solution is placed in a graduated cylinder and a small amount of acid is added to initiate a reaction. Observe as a yellow layer forms and begins moving down the graduated cylinder. Kit Includes: 1 x 5 ml Toluidine Blue, 0.5% Solution 1 x 30 ml Sulfuric Acid, 3.0M Solution 1 x 250 ml Potassium Chlorate/Sodium Sulfite Solution
