WebReaction of an acid with a carbonate is: 2H + + CO 32- CO 2 + H 2 O. From the stoichiometry 2 moles of acid is required to react with 1 mole of carbonate. Moles of hydrochloric acid = 0.06285 moles therefore moles of carbonate = 0.06285/2 moles = 0031425. The mass of the unknown carbonate = 2.64g. WebFor this titration, take 25.00 mL aliquots of your antacid/hydrochloric acid solution. 6. Write a balanced equation for the reaction between sodium hydroxide and hydrochloric acid. 1 NaOH(aq) + HCl(aq) -> NaCl(aq) + H2O(l) 7.
