Why does a titrated sample that is fuschia with phenolphthalein turn colorless when the solution is blown into? HINT: Use chemistry and properly balanced chemical equations to support your statement.
When you blow into the solution you are adding CO2 to the solution. The CO2 reacts with water to form H2CO3 and that ionizes to produce H^+. That lowers the pH of the solution and the phenolphthalein turns the acid color which is colorless. You write the equations.
