Detailed explanation-1: -In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic. Solutions of equal solute concentration are isotonic.

Detailed explanation-2: -A hypotonic solution has a lower solute concentration compared to the intracellular solute concentration. When a red blood cell is placed in a hypotonic solution, there will be a net movement of free water into the cell.

Detailed explanation-3: -A solution with a lower solute concentration as compared to a solvent is called a hypotonic solution. In contrast, a solution with a high solute concentration as compared to a solvent is called a hypertonic solution.

Detailed explanation-4: -If the solution in the surrounding has a lower solute concentration as compared to the solute concentration inside the cell, then the solution is called hypotonic. Or, if the surrounding solution has high solvent concentration compared to the inside of the cell, then it is hypotonic solution.

Detailed explanation-5: -A solution containing less amount of solute is called dilute solution. Dilution is the process of decreasing the concentration of a solute in solution, usually by mixing with more solvent.
