Question

Assertion : carbonic acid is a weak acid reason : it ionized completely in aqueous solution

Answer 1

Answer:

Assertion is true but reason is false

Answer 2

The assertion is true but the reason is wrong regarding carbonic acid.

• Carbonic acid is represented by the formula H2CO3. The acid dissociates partially into its constituent ions and thus, is a weak acid.
• The acid or base that dissociates completely in an aqueous solution is strong acid or base respectively.
• Example of strong acid is hydrochloric acid, nitric acid and example of a strong base is sodium hydroxide and potassium hydroxide.
• Example of the weak acid is formic acid and acetic acid and example of a weak base is ammonia and aluminium hydroxide.
