28 Which compound yields H + ions as the only positive ions in an aqueous solution?
MrMuchimi

Answer: (4) CH_3COOH

Explanation:-

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydronium ions (H_3O^+) in water.

1. KOH is a strong electrolyte and thus dissociate in water.KOH\rightarrow K^++OH^-

2. CH_3OH is a non electrolyte and thus do no dissociate in water.

CH_3COOH\rightarrow no reaction

3. NaOH is a strong electrolyte and thus dissociate in water.

NaOH\rightarrow Na^++OH^-

4. CH_3COOH is a weak electrolyte and thus partially dissociate in water.

CH_3COOH\rightleftharpoons CH_3COO^-+H^+
