Answer to Question #36832 in Physical Chemistry for praja

Question

ph of 0.01 M acetic acid is 3. the degree of conisationation of acitic acid is
a) 0.1% b) 10% c) 1% d) 0.01%

Answer 1

pH = 3, => [H+] = 0.001 M;
[HAc] = 0.01 M;
degree of conisationation = [H+]/[HAc] = 0.1 = 10%.
So the correct answer is "b".
