Question
pH of a 0.1 M monobasic acid is measured to be 2. Its osmotic pressure at a given temperature TK is ?
Options
A.0.1 RT
B.0.11 RT
C.1.1 RT
D.0.01 RT
Solution
H+ = Cα C = 0.1 M
10-2 = 0.1α H+ = 10-2
α = 0.1 i = 1 + α(N - 1) = 1 + 0.1(2 - 1)
= 1.1
π = CRTi
= 0.1 × RT × 1.1 = 0.11 RT
10-2 = 0.1α H+ = 10-2
α = 0.1 i = 1 + α(N - 1) = 1 + 0.1(2 - 1)
= 1.1
π = CRTi
= 0.1 × RT × 1.1 = 0.11 RT
