Question

Substances which dissolve in water to give ions or substances that dissociate into ions when dissolved in water is called-?

• A. Electrolytes
• B. Elements
• C. Acids
• D. None of these

Answer 1

Answer: (A)

Electrolytes

Electrolytes when dissolved in water dissociates completely or partially to form ions. Example $NaCl$ when dissolved in water dissociates to $N{a}^{+}$ and $C{l}^{-}$ ions. Thus $NaCl$ is a good electrolyte.
Electrolytes when dissolved in water can conduct electricity. Because positive and negative ions are present in the solution because of the dissociation of the electrolytes in the solution.
