Question

Sodium hydroxide is _______.

Answer 1

1. Sodium hydroxide is a strong base which dissociates completely in aqueous solution.

2. Strong bases are strong electrolytes as they almost dissociates in pure water .

3. Chemical equation for its dissociation:

$$\begin{gathered} \mathrm{NaOH}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\rightleftharpoons {\mathrm{Na}}^{+}\left(\mathrm{aq}\right)+{\mathrm{OH}}^{-}\left(\mathrm{aq}\right) \\ (\mathrm{Sodium}(\mathrm{Water})(\mathrm{Sodium}\mathrm{ion})(\mathrm{Hydroxide}\mathrm{ion}) \\ \mathrm{hydroxide}) \end{gathered}$$

So, sodium hydroxide is strong electrolyte.
