Solution

## The correct options are A 1 litre B 10 litre C 100 litre D 25 litreBefore dilution, the pH is 1. This corresponds to 0.1 M hydrogen ion concentration. When the solution is diluted 10 times, its hydrogen ion concentration will be 0.01 M ⇒ pH =2.To this solution, when a solution with pH = 2 is added, the hydrogen ion concentration and pH of the resulting mixture will remain the same. This is irrespective of the volume of the solution added.
