If the pH values of solutions X, Y and Z are 13, 6 and 2 respectively then
does the pH value of a solution increase or decrease when a base is added to it '? Why?

Text Solution

Verified by Experts

pH value increases. Because, if we add base to acid first neutralisation takes place, after that pH of the solution increases.
