It plays a crucial role in rehydration, drug administration, cell cultures, and laboratory experiments. Let's take a closer look at the isotonic solution.



A complex term but a vital role. An isotonic solution is a solution that has the same concentration of solutes as the medium it is in contact with. This means that the osmotic pressure across the cell membrane is balanced, allowing cells to maintain their volume and shape.

Understanding isotonic solutions is crucial in many fields, including biology, medicine, and chemistry, for several reasons:

Biology: Living cells need an isotonic environment to function properly. Isotonic solutions are used in cell biology to keep cells in culture under optimal conditions, preventing drastic osmotic pressure changes that could damage or deform the cells.
