Question

Choose the correct answers from the alternatives given.
When a cell is placed in 0.5 M solution of salt and no change in the volume of the cell is observed; the concentration of cell sap would be

• A. 0.5 M
• B. 0.05 M
• C. 5.0 M
• D. 50 M

Answer 1

The correct option is A 0.5 M

When the concentrations of both the solution (cell sap as well surrounding solution) are same, there is no net movement in the cell. Such solutions are called isotonic solutions. Since it is specified that no change in volume occurs it means that the concentration of the cell sap will be same as that of the concentration of salt.

Hence, the correct answer is '0.5 M'.
