Question

Give an example of a basic salt.

Answer 1

Basic salt:-

1. The type of salt formed due to reaction of a weak acid and a strong base is called a basic salt.
2. The type of salt formed by this reaction has a more basic character to it.
3. This salt has a pH value more than 7.
4. For example Sodium acetate$\left({\mathrm{CH}}_3\mathrm{COONa}\right)$ is a basic salt.
5. It is formed when Acetic acid ${\mathrm{CH}}_3\mathrm{COOH}$ (weak acid) is reacted with Sodium hydroxide $\mathrm{NaOH}$(strong base).
6. The balanced reaction is: $\underset{\mathrm{Acetic}\mathrm{acid}}{{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Sodium}\mathrm{hydroxide}}{\mathrm{NaOH}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{acetate}}{{\mathrm{CH}}_3\mathrm{COONa}\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$

Therefore, an example of a basic salt is Sodium acetate$\left({\mathrm{CH}}_3\mathrm{COONa}\right)$
