When potassium hydroxide solution is neutralised with an acid, there is a temperature change.
A student is given dilute nitric acid and dilute ethanoic acid of the same concentration in mol dm−3\text{mol dm}^{-3}mol dm−3.
Devise a plan to compare the temperature changes produced when potassium hydroxide solution is neutralised with each of these two acids.
