J is hydrochloric acid prepared by dissolving a volume, V of hydrogen chloride gas per dm3of the solution at s. t.p.
L is a solution containing 4.50g of NaHCO3 per 500cm3.
J was put into the burette and titrated against 25cm3 portions of L using methyl
orange as indicator. Titration was repeated to obtain consistent titre values.
