Question
In isotonic solutions:
(i) Solute and solvent both are same.
(ii) Osmotic pressure is same.
(iii) Solute and solvent may or may not be same.
(iv) Solute is always same solvent may be different.
Solution
(ii) Osmotic pressure is same.
(iii) Solute and solvent may or may not be same.
Explanation:
Two dilute solutions with same molar concentration at given temperature have also the same osmotic pressure. Such solutions are known as isotonic or iso-osmotic solution.
