Question

When the specific conductivity of a weak

electrolyte is plotted on the y-axis of graph and

the concentration along the x-axis, the graph

shows :

• A. Steady increase in conductivity with concentration
• B. The conductivity rising to a maximum then remaining constant
• C. A steady decrease in conductivity with concentration
• D. The conductivity rising to a maximum then beginning to fall again.

Answer 1

Answer: (B)

The conductivity rising to a maximum then remaining constant

The specific conductance of solution increases with increase in concentration due to increase in the number of ions per unit volume of the solution.
The specific conductance reaches a maximum value and then remain constant as the concentration reaches a maximum value.
