A student investigated a property of acids M and N by reacting equal volumes of acid M and N of the same concentration with equal volumes of 2 M potassium hydroxide. The results were recorded in the table below

a) Which of the acids is likely to be a weak acid? Explain.
b) Write the equation for the reaction between ethanoic acid and potassium hydroxide.

---

a) Acid N. The rise in temperature is minimum showing that the acid is partially ionized hence some energy
is used to ionize its molecules fully

b) $CH_3COOH_{(aq)} + KOH_{(aq)} \rightarrow CH_3COOK_{(aq)} + H_2O_{(l)}$
