The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
A strong electrolyte ionises almost completely in water. A weak electrolyte ionises only slightly and sets up an equilibrium.
Step 2: Detailed Explanation:
NaOH and KOH are strong bases and dissociate completely into metal ions and \(\text{OH}^-\).
HI is a strong acid and ionises fully into \(\text{H}^+\) and \(\text{I}^-\).
\(\text{NH}_3\) reacts with water only to a small extent:
\[ \text{NH}_3 + \text{H}_2\text{O} \rightleftharpoons \text{NH}_4^+ + \text{OH}^- \]
Its \(K_b\) is about \(1.8\times10^{-5}\), so very few molecules ionise.
Step 3: Final Answer:
\(\text{NH}_3\) is the weak electrolyte, option (A).
Final Answer:
Ammonia is a weak base and a weak electrolyte. \[ \boxed{\text{(A) }\text{NH}_3} \]
