Question

Which of the following are weak electrolytes?

HNO₃
HF
NH₃
LiBr

a. HNO₃, HF, NH₃, LiBr
b. HF, LiBr
c. HNO₃, NH₃, LiBr
d. HF, NH₃

Answer 1

The weak electrolytes are HNO₃, HF, NH₃, LiBr.

Step-by-step explanation:

A weak electrolyte is a substance that only partially dissociates into ions when dissolved in water. The compounds that can behave as weak electrolytes in the given options are:

• HNO₃
• HF
• NH₃
• LiBr

These compounds partially dissociate into ions when in water, making them weak electrolytes. The correct option is (a) HNO₃, HF, NH₃, LiBr.
