25.0cm3 of aqueous sodium hydroxide is pipetted into a conical flask. A few drops of an indicator are added. Using a burette, dilute sulphuric acid is slowly added until the indicator just changes colour. The volume of acid needed to neutralize the alkali is noted. Suggest how you would continue the experiment to obtain pure, dry crystals of sodium sulphate-10- water
