in which kind of solution is the concentration of solutes the same inside and outside of the cell?

The kind of solution in which the concentration of solutes is the same inside and outside of the cell is called an isotonic solution. In an isotonic solution, there is no net movement of water into or out of the cell because the solute and water concentrations are equal on both sides of the cell membrane. This equilibrium maintains the cell's normal shape and volume without swelling or shrinking.
