MCQ

Electrolytes when dissolved in water dissociates into ions because

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

✓

Answer

Correct option: D.

The forces of electrostatic attraction are broken down by water

d
Electrolytes when dissolved in water dissociates completely or partially to form ions. Example $NaCl$ when dissolved in water dissociates to $Na ^{+}$ and $Cl ^{-}$ 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.
