Question

Electrolytes when dissolved in water dissociates into ions because:

• A. They are unstable
• B. The water dissolves it
• C. The force of repulsion increases
• D. The forces of electrostatic attraction are broken down by water.

Answer 1

Answer: (D)

The forces of electrostatic attraction are broken down by water.

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.

Hence$\text{option C is a correct answer.}$
