Two solutions which have the the same osmotic pressure are called isotonic solutions.

Isotonic solutions : Solutions having same osmotic pressure at a given temperature are called isotonic solutions.
e.g. : Blood is isotonic with `0.9%((W)/(V))” NaCl”` [Saline]

Isotonic solutions are those solutions that have the same osmotic pressure at a given temperatrue.

Two solutions having same osmotic pressure at a given temperature are called isotonic solutions. When such solutions are separated by semipermeable membrane no osmosis occurs between them.
