pH of a 1 M of a weak monobasic acid(degree of dissociation is "α" ) is found to be 2 . Hence its osmotic pressure at a given temperature T K is -

Options:

Answer:

Solution:

$HA ⇌ H^{+} + A^{-} (C - C α) C α C α [H^{+}] = 1 0^{- 2} ∵ pH = 2 C α = 1 0^{- 2} 1 \times α = 1 0^{- 2} α = 1 0^{- 2} π = iCRT = (1 + α) CRT = (1 + 1 0^{- 2}) \times 1 RT 1.01 RT$
