A student repeated a titration to determine the exact volume of dilute hydrochloric acid required to neutralise 25.0 cm3 of sodium hydroxide solution.
The initial volume measuring steps were completed carefully using a volumetric pipette and a burette.
Explain two other practical steps that should be taken during the titration to ensure that an accurate titre volume is obtained.
