Question

What is isotonic solution.

Answer 1

1. Two solutions having the same osmotic pressure across a semipermeable membrane is referred to as isotonic solution. It has the same osmolarity (solute concentration), as another solution.
2. A solution is isotonic when its effective mole concentration is the same as that of another solution.
3. This state provides the free movement of water across the membrane without changing the concentration of solutes on either side.
