Isotonic Solutions and Degree of Dissociation of Na₂SO₄

## Isotonic Solutions and Degree of Dissociation of Na₂SO₄ Isotonic solutions are those that have the same osmotic pressure at a given temperature. The comparison of osmotic pressures allows for the determination of the degree of dissociation of electrolytes when their solutions are isotonic with non-electrolyte solutions. This concept is...

What does it mean for two solutions to be isotonic?

They have the same osmotic pressure.

Which formula is used to calculate the osmotic pressure of a solution when the van't Hoff factor is considered?

Pi = iCRT

If the various terms in the given below expressions have usual meanings, the van't Hoff factor (i) cannot be calculated by which one of the following expressions?

$\pi V=\sqrt{i } nR T$

Assume the given salts are 100% dissociated in the aqueous solutions. The value of Van't Hoff factor will be maximum for:
