QUESTION: 1

Solution:
QUESTION: 2

Solution:
QUESTION: 3

### Which of the following statements is correct?

Solution:

The correct answer is Option D.

The molar conductivity increases with decrease in concentration both, for weak and strong electrolytes.

This is because the total volume, V, of a solution containing one mole of electrolyte also increases. It has been found that a decrease in k on dilution of a solution is more than compensated by an increase in its volume.

QUESTION: 4
