Question

Determine the osmotic pressure of a solution prepared by dissolving 25 mg of K₂SO₄ in 2 liter of water at 25° C, assuming that it is completely dissociated.

Open in App

Solution

When K₂SO₄ is dissolved in water, ions are produced.

Total number of ions produced = 3

i =3

Given,

w = 25 mg = 0.025 g

V = 2 L

T = 25⁰C = (25 + 273) K = 298 K

Also, we know that:

R = 0.0821 L atm K^-1mol^-1

M = (2 × 39) + (1 × 32) + (4 × 16) = 174 g mol^-1

Appling the following relation,
