Question

Is potassium chromate an electrolyte?

Answer 1

Explanation:

1. Electrolyte: The substance which dissociates in an aqueous solution called the electrolyte.
2. Electrolytes are of two types first one is a strong electrolyte and another one is a weak electrolyte.
3. Potassium chromate is a strong electrolyte as it completely dissociates.
4. The formula of potassium chromate is ${\mathrm{K}}_2{\mathrm{CrO}}_4$.
5. It dissociates as:

${\mathrm{K}}_2{\mathrm{CrO}}_4\left(\mathrm{s}\right)\to 2{\mathrm{K}}^{+}\left(\mathrm{aq}\right)+{\mathrm{CrO}}_4^{2-}\left(\mathrm{aq}\right)$

Hence, potassium chromate is an electrolyte.
