Question
What will be the effect of adding 100 ml of 0.001 M-HCl solution to 100 ml of a solution having 0.1 M-HA? The acid dissociation constant of HA is 10−5.
Options
A.The degree of dissociation of HA will decrease but the pH of solution remains unchanged.
B.The degree of dissociation of HA remains unchanged but the pH of solution decreases.
C.Neither degree of dissociation nor pH of solution will change.
D.The degree of dissociation as well as pH of solution will decrease.
Solution
As on adding HCl, [H+] is not changing and will remain unchanged.
