Equilibrium Question 914

Question: 10 mL, of a strong acid solution of pH=2.000 are mixed with 990 mL of another strong acid solution of pH=4.000 . The pH of the resulting solution will be:

Options:

A) 4.002

B) 4.000

C) 4.200

D) 3.7

Show Answer

Answer:

Correct Answer: D

Solution:

[H+] after mixing =102×10+104×9901000

0.1=0.09901000=0.19901000=1.99×104

pH=40.3=3.7
