Question

What is strong acid and weak base.Give suitable example of each

Answer 1

Answer:

strong acid  or a strong base completely ionizes (dissociates) in a solution. In water, one mole of a strong acid HA dissolves yielding one mole of H+ (as hydronium ion H3O+) and one mole of the conjugate 

weak acid or a weak base only partially dissociates. At equilibrium, both the acid and the conjugate base are present in solution

Answer 2

Explanation:

A strong acid or a strong base completely ionizes (dissociates) in a solution. In water, one mole of a strong acid HA dissolves yielding one mole of H+ (as hydronium ion H3O+) and one mole of the conjugate base, A−. Essentially, none of the non-ionized acid HA remains.

Strong acid: HA + H2O → A-(aq) + H3O+(aq)

Strong base: BOH + H2O → B+(aq) + OH-(aq)

Examples of strong acids and bases are given in the table below. In aqueous solution, each of these essentially ionizes 100%.

A weak acid or a weak base only partially dissociates. At equilibrium, both the acid and the conjugate base are present in solution

Weak acid: AH + H2O ↔ A-(aq) + H3O+(aq)

Weak base: BOH + H2O ↔ B+(aq) + OH-(aq) or

B + H2O ↔ BH+(aq) + OH-(aq)
