Which compound, when dissolved in water, conducts electricity and forms a basic solution?

A
HCI
B
$\mathrm{CH}_3 \mathrm{COOH}$
C
$\mathrm{CH}_3 \mathrm{OH}$
Correct answer
D
NaOH

Solution

Strong electrolyte is an ionic compound that dissociates completely in water \& conducts electricity.From the given options, only NaOH and HCl are strong electrolytes and NaOH alone would form a basic solution when dissolved in water. NaOH is a strong electrolyte. It is an alkali-a water soluble strong base.

Hence, the correct answer is option: 'D'.
