Question

Acetic acid is weak acid and ammonia is weak base. discuss the term weak.

Answer 1

acetic acid is weak acid becoz it produces less hydrogen ions and ammonia is weak base becoz it produces less OH ions

Answer 2

Explanation:

If an acid which is less than 100% ionizes in solution is known as weak acid.

For example: $\mathrm{HF}, \ \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}, \ \mathrm{H}_{3} \mathrm{PO}_{4}$

If a base which is less than 100% ionizes in solution is known as weak base.

For example: $\mathrm{NH}_{3}, \ \mathrm{NH}_{4} \mathrm{OH}, \ \mathrm{C}_{5} \mathrm{H}_{5} \mathrm{N}$

Acetic acid is dissociates into ions but it does not ionize 100% therefore it is considered as weak acid.

$\mathrm{CH}_{3} \mathrm{COOH} \rightarrow \mathrm{H}^{+}+\mathrm{CH}_{3} \mathrm{COO}^{-}$

Ammonia dissociates into ions but it does not ionize 100% therefore it is considered as weak base.
