Question

In the conductometric titration of hydrochloric acid against ammonium hydroxide,

• A. The conductance increases till the endpoint with the volume of NH4OH added.
• B. The conductance remains more or less constant till the endpoint.
• C. The conductance remains more or less constant after the endpoint.
• D. The conductance increases after the endpoint with the volume of NH4OH added.

Hint:

After neutralization, the concentrations of the ions in the solution stabilize, resulting in constant conductance.

Answer 1

The Correct Option is C

In the titration of HCl with $NH_4OH$, the conductance is initially high due to the presence of strong ions. After the endpoint, when the acid is neutralized, the conductance stabilizes and remains nearly constant.
