Question

pH of a 0.1 M monobasic acid (HA) is measured to be 2. Its osmotic pressure at temperature T K is, 0.1 RT, 0.11 RT, 1.1 RT, 0.01 RT

[ H + ] = C α ; [ H + ] = 1 0 - p H So C α = 1 0 - 2 0.1 α = 1 0 - 2 α = 0.1 α = i - 1 n - 1 ; 0.1 = i - 1 2 - 1 i = 1.1 So π = i C R T = 1.1 × 0.1 × R T = 0.11 R T
