Answer 1

Answer:The amount of the base (NaOH) in a solution can be determined by measuring very accurately the amount of solution required to react with a known amount of acid (KHP). One mole of KHP contains one mole of H+ that can react with one mole of sodium hydroxide, which contains one mole of OH
