Question 78

A student carries out an experiment to measure the temperature change when different volumes of sodium hydroxide solution are added to dilute hydrochloric acid.

The method for the experiment is:

  • Measure 25 cm3 of dilute hydrochloric acid and pour into a container
  • Record the initial temperature of the acid
  • Add 25 cm3 of sodium hydroxide solution
  • Stir the mixture and record the maximum temperature reached

State a suitable container to use for the reaction mixture in this experiment to minimize heat loss.
