Question

An aqueous solution of the salt is acidic. Which of the following acids and bases react to give this salt. a) Strong acid and strong base b) Strong acid and weak base c)Weak acid and strong base d) Weak acid and weak base

Answer 1

b.) strong acid and weak base

Answer 2

Option B is the correct answer.

• A strong acid reacts with a weak base in an aqueous solution to create an acidic solution because of the existence of free hydrogen (H+) ions. This is an account of the reason that the base is not ionized. For example, HCl is a strong acid and ammonium hydroxide (NH4OH) is a weak base.
• A solution of strong acid and a strong base is always neutral.
• A solution of a weak acid and strong base is basic in the property.
• A solution of a weak acid and weak base may be acidic, basic or neutral counting upon their comparative stability.

Hence, option B is the correct answer.
