Dissociation constant of mono basic acids A, B, C and D are 6 x 10-4, 5 x 10-5, 3.6 x 10-6 and 7 x 10-10respectively. The pH values of their 0.1M aqueous solution are in the order.
A
D> C > B > A
B
A > B >C > D
C
D > C > A > B
D
None
Answer
D> C > B > A
Explanation
Solution
Concentration of Solutions are same therefore [H+] depends only on Dissociation constant.
