Q17 / 150 · MHT CET 2026 (16 April Shift 1) · Chemistry
Identify from following a weak electrolyte based on their dissociation nature in aqueous medium.
- Correct answerA$\text{NH}_3$
- B$\text{NaOH}$
- C$\text{KOH}$
- D$\text{HI}$
Solution
Strong electrolytes dissociate completely in an aqueous solution.
$\text{NaOH}$ and $\text{KOH}$ are strong bases and dissociate completely into their respective ions.
$\text{HI}$ is a strong acid and also dissociates completely into ions.
$\text{NH}_3$ is a weak base and dissociates only partially in an aqueous solution to form $\text{NH}_4^+$ and $\text{OH}^-$ ions.
Thus, $\text{NH}_3$ is a weak electrolyte.
Answer: $\text{NH}_3$
$\text{NaOH}$ and $\text{KOH}$ are strong bases and dissociate completely into their respective ions.
$\text{HI}$ is a strong acid and also dissociates completely into ions.
$\text{NH}_3$ is a weak base and dissociates only partially in an aqueous solution to form $\text{NH}_4^+$ and $\text{OH}^-$ ions.
Thus, $\text{NH}_3$ is a weak electrolyte.
Answer: $\text{NH}_3$
Hence, the correct answer is option: 'A'.
