Current Question (ID: 18199)

Question:

$\text{The cell constant of a conductivity cell-}$

Options:

1. $\text{Changes with the change of electrolyte.}$
2. $\text{Changes with the change of concentration of electrolyte.}$
3. $\text{Changes with the temperature of the electrolyte.}$
4. $\text{Remains constant for a cell.}$

Solution:

$\text{HINT: (Cell constant) } x = \frac{l}{A}$ $\text{Explanation:}$ $\text{The cell constant is defined as the ratio of the length of the object and the area of the cross-section.}$ $x = \frac{l}{A}$ $\text{Since, } l \text{ and } A \text{ remain constant for any particular object, hence the value of the cell constant always remains constant.}$
