Question

pH of 0 .1 M aqueous solution of weak monoprotic acid HA is 2 . Calculate osmotic pressure of this solution at 27 o C . Take solution constant R = 0 .082 L atm/K-mol, 2.46 atm, 3.5 atm, 3.05 atm, 2.7 atm

MARKS App · Accepted Answer

H + = 0.1 × ∝ = 1 0 - 2 ∴ ∝ = 0.1 π = iCRT = 1 .1 × 0 .1 × 0 .082 × 300 = 2 .7 atm
