Question

Which among the following sets of solutions can be used as electrolytes?

[1 mark]

• A. Copper sulphate, carbon tetrachloride
• B. Sugar, methanol
• C. Common salt, copper sulphate
• D. Kerosene, carbon tetrachloride

Answer 1

The correct option is C Common salt, copper sulphate

Sugar, kerosene, and carbon tetrachloride do not form ions in their aqueous solutions. Hence, they do not conduct electricity and cannot be used as electrolytes.

On the other hand, copper sulphate and common salt (NaCl) dissociate into ions in the aqueous solutions, and hence they can be used as electrolytes.
