    How do reactant proportions affect the products of a chemical reaction?

    Is it correct that if you alter the proportions of the reactants of many chemical reactions, especially step-wise, the products will change? Here is an example, please tell me if it is right or not: KOH + H2SO4 ==> KHSO4 + H2O 2KOH + H2SO4 ==> K2SO4 + 2H2O
