what is hypertonic solution

A hypertonic solution is a solution that has a higher concentration of solutes compared to another solution to which it is compared. When a cell is placed in a hypertonic solution, water will move out of the cell, causing it to shrink. Hypertonic solutions have a higher osmotic pressure than the solution to which they are compared. Three terms are used to describe whether a solution will cause water to move into or out of a cell: hypertonic, hypotonic, and isotonic. A hypertonic solution will cause water to move out of the cell, while a hypotonic solution will cause water to move into the cell. In an isotonic solution, there is no net water movement, so there is no change in the size of the cell.
