A student determined the precise volume of dilute sulfuric acid required to neutralise 20.0 cm3 of sodium hydroxide solution via titration.
The student then combined this exact volume of dilute sulfuric acid with 20.0 cm3 of the sodium hydroxide solution in a clean beaker, ensuring no indicator was present.
Devise a practical method to obtain a pure, dry sample of sodium sulfate crystals from this neutralised solution.
