Answer: The difference in the pH values of the two solutions is 2.7
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
a) For solution A, let
= 
Putting in the values:
b) For solution B,
=
Putting in the values:
Thus the difference in pH will be (4-1.3)= 2.7.
