Answer:
Calculate the concentration of the hydrochloric acid.
Volume of sodium hydroxide solution = 25.00 ÷ 1000 = 0.0250 dm 3
Amount of sodium hydroxide = 0.200 × 0.0250 = 0.005 mol.
From the equation, 0.005 mol of NaOH reacts with 0.005 mol of HCl.
Volume of hydrochloric acid = 22.70 ÷ 1000 = 0.0227 dm 3
