CBSE: Class 12
Definition: Isotonic Solutions
Two or more solutions having the same osmotic pressure are said to be isotonic solutions.
CBSE: Class 12
Definition: Hypertonic Solutions
If two solutions have unequal osmotic pressures, the more concentrated solution with higher osmotic pressure is said to be a hypertonic solution.
For example, if osmotic pressure of sucrose solution is higher than that of urea solution, the sucrose solution is hypertonic to urea solution.
CBSE: Class 12
Definition: Hypotonic Solutions
The more dilute solution exhibiting lower osmotic pressure is said to be a hypotonic solution.
For example, if osmotic pressure of sucrose solution is lower than that of urea solution, the sucrose solution is hypotonic to urea solution.
