Problem
A titration experiment was performed to find the concentration of a solution of sodium hydroxide. It was found that an average titre of 20.45 cm3 of sulfuric acid with a concentration of 0.200 mol dm-3 was required to neutralise 25.00 cm3 of the sodium hydroxide solution.
(1) Calculate the number of moles of sulfuric acid used per titre.
(2) Give the equation for the reaction.
(3) Use the balanced equation to find the number of moles of sodium hydroxide per titre.
(4) Calculate the concentration of the sodium hydroxide solution.
