Give examples of Basic salt, Complex Salt and Normal Salt.

Normal salt:-

1. Salts are the ionic compounds that are formed by the neutralisation reaction.
2. These are the products of an acid and a base.
3. For example, when Sodium hydroxide reacts with Hydrochloric acid it forms a normal salt of Sodium chloride.

$\underset{\mathrm{Sodium}\mathrm{hydroxide}}{\mathrm{NaOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrochloric}\mathrm{acid}}{\mathrm{HCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{chloride}}{\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$

Complex salt:-

1. Complex salt is salt where various complex ions are attached to the central metal ion.
2. Example of such type of complex salt is: Potassium ferrocyanide ${\mathrm{K}}_4\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]$, Potassium argentocyanide $\mathrm{K}\left[\mathrm{Ag}{\left(\mathrm{CN}\right)}_2\right]$

Basic salt:-

1. These are the salts that are formed by the neutralisation reaction of a weak acid and a strong base.
2. For example, when a weak acid like Acetic acid reacts with a strong base like Sodium hydroxide, it forms a basic salt of Sodium acetate:

$\underset{\mathrm{Sodium}\mathrm{hydroxide}}{\mathrm{NaOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Acetic}\mathrm{acid}}{{\mathrm{CH}}_3\mathrm{COOH}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{acetate}}{{\mathrm{CH}}_3\mathrm{COONa}\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$

Therefore, examples of normal salt- Sodium chloride$\mathrm{NaCl}$, basic salt- Sodium acetate${\mathrm{CH}}_3\mathrm{COONa}$, and complex salt- Potassium ferrocyanide${\mathrm{K}}_4\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]$
