Publication 12407

Price: FREE

Add a pink cobalt chloride solution to a colorless solution containing potassium sodium tartrate and hydrogen peroxide and watch as a very obvious green-colored complex forms. As the reaction ends, the solution will return to its original pink color—indicating that the cobalt chloride catalyst is not used up in the reaction.
