CAIE IGCSE Chemistry 7.1.12 Ethanoic acid is a weak acid, as shown

Practise representing ethanoic acid as a weak acid by completing reversible dissociation equations with H+(aq) and ethanoate ions.

Exam points

complete CH3COOH(aq) ⇌ H+(aq) + CH3COO-(aq) with the reversible arrow
identify ethanoic acid as partially ionised from its aqueous dissociation equation

[Maximum number: 3]

Solid sodium hydroxide is a base which dissolves to form an aqueous solution, NaOH(aq).

Ethanoic acid, $\mathrm{CH}_{3} \mathrm{COOH}$ , is a weak acid.

Complete the symbol equation to show the dissociation of ethanoic acid.
