Ncert Exercises & Solutions

The cell constant of a conductivity cell-

1.	Changes with the change of electrolyte.
2.	Changes with the change of concentration of electrolyte.
3.	Changes with the temperature of the electrolyte.
4.	Remains constant for a cell.

HINT: (Cell constant)

x = \frac{l}{A}

Explanation:

The cell constant is defined as the ratio of the length of the object and the area of the cross-section.

x = \frac{l}{A}

Since, l and A remain constant for any particular object, hence the value of the cell constant always remains constant.
