Question
A volume of 10 ml of a strong acid solution of pH = 2.0 are mixed with 990 ml of a buffer solution of pH = 4.0. The pH of the resulting solution will be
Options
A.4.2
B.6.0
C.4.002
D.4.0
Solution
On adding acid, PH should decrease slightly. As none of the option is slightly less than 4.0, answer is 4.0
