A colorless solution is poured from a large beaker into four smaller beakers producing solutions of "strawberry soda," "blueberry soda," "red wine," and "water." Mixing the resulting solutions from the first three beakers produces "red wine." The three beakers are refilled with wine and subsequently all four are poured back into the large beaker to produce water. Teacher Demonstration Notes included. Enough materials are included to perform the demonstration seven times.
Concepts: Acid–base indicators, complex ions.
Time Required: 15 minutes
Chemicals Provided: Phenolphthalein and thymolphthalein indicator solutions, ammonium hydroxide, iron(III) chloride, hydrochloric acid, sodium fluoride solution and potassium thiocyanate solution.
