Use these results as an example: A titration is carried out and 0.04dm 3 hydrochloric acid neutralises 0.08dm 3 sodium hydroxide of concentration 1.00 mol/dm 3. Calculate the concentration of the hydrochloric acid. moles of sodium hydroxide = concentration x volume = 1.00 x 0.08 = 0.08 mol concentration = 0.08 0.04 = 2 mol/d m 3 HCl + NaOH NaCl + H 2 O, so reaction is 1 : 1
