To compare the heat of neutralisation of a strong acid (hydrochloric acid) and a weak acid (ethanoic acid) with a strong alkali (sodium hydroxide).

If you need help breaking down a specific concept from your workbook, let me know: Which are you currently working on?
A student wants to investigate the effect of the strength of acids on the heat of neutralisation. The student uses hydrochloric acid, HCl, and ethanoic acid, CH₃COOH, to neutralise sodium hydroxide, NaOH.
| Experiment | Acid used | Initial temperature of NaOH (°C) | Initial temperature of Acid (°C) | Average initial temperature (°C) | Highest temperature of mixture (°C) | Temperature change, $\Delta T$ (°C) | | :--- | :--- | :--- | :--- | :--- | :--- | :--- | | I | Hydrochloric acid (HCl) | $T_1$ | $T_2$ | $\fracT_1 + T_22$ | $T_max$ | | | II | Ethanoic acid (CH₃COOH) | $T_3$ | $T_4$ | $\fracT_3 + T_42$ | $T_max$ | |

Malaysian SPM candidates often use the workbook to master their Sijil Pelajaran Malaysia (SPM) syllabus. This workbook reinforces difficult concepts like electrochemistry, thermochemistry, and organic chemistry. However, learning effectively requires immediate feedback, which makes finding accurate answer keys essential.
