Question

Is sodium sulfide an electrolyte?

Answer 1

Explanation:

1. Sodium sulfide: The formula of sodium sulfide is ${\mathrm{Na}}_2\mathrm{S}$
2. Sodium sulfide is dissociated in an aqueous solution as -

${\mathrm{Na}}_2\mathrm{S}\left(\mathrm{aq}\right)\to 2{\mathrm{Na}}^{+}\left(\mathrm{aq}\right)+{\mathrm{S}}^{2-}\left(\mathrm{aq}\right)$

1. Sodium sulfide has a relatively high dissociation constant.
2. It's a potent(strong) electrolyte.

Hence, sodium sulfide is a strong electrolyte.
