Question

Is $\mathrm{NaCl}$ it An Acid or Base?

Answer 1

$\mathbf{NaCl}$ is a neutral. it is formed from the reaction between strong acid Hydrochloric Acid ($\mathbf{HCl}$) and the strong base Sodium Hydroxide ($\mathbf{NaOH}$).

1. As per Arrhenius's theory the reaction between acid and base results in the formation of neutral salt Sodium Chloride ($\mathbf{NaCl}$) and Water (${\mathbf{H}}_{\mathbf{2}}\mathbf{O}$).
2. $\mathrm{NaOH}\left(\mathrm{aq}\right)+\mathrm{HCl}\left(\mathrm{aq}\right)\to \mathrm{NaCl}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$
3. This reaction is called a neutralization reaction.

Arrhenius's theory: The Arrhenius principle states that an acid is a chemical that releases an ${\mathbf{H}}^{\mathbf{+}}$ ion when dissolved in water. This increases the number of ${\mathbf{H}}^{\mathbf{+}}$ ions present in the solution, A base is a chemical that dissolves in an aqueous solution and ionizes to an ${\mathbf{OH}}^{\mathbf{-}}$ ion. There are a lot of ${\mathbf{OH}}^{\mathbf{-}}$ ions in the solution.

Hence, $\mathbf{NaCl}$ is a neutral salt.
