Equilibrium Question 315

Question: pH of a solution produced when an aqueous solution of pH 6 is mixed with an equal volume of an aqueous solution of pH 3 is about [KCET 2001]

Options:

A) 3.3

B) 4.3

C) 4.0

D) 4.5

Show Answer

Answer:

Correct Answer: A

Solution:

pH=6 means [H+]=106M

pH=3 means [H=]=103M After mixing, Total [H+]=(106+103)2

=1.001×1032

=5.005×104

pH=4log5.005 ; pH=3.301 .
