I want to know how to do the graph!

Answer 1

By adding acid continuously, the pH of the solution decreases gradually.

This is the case similar to the addition of base (where the pH of the solution increases gradually).

Then, the curve for the addition of acid to the solution decreases, i.e. starting from the upper point and ending at the lower point.
