Why, when an ammonia solution is titrated with a strong acid, the #pH# remains relatively constant up to the addition of a stoichiometric quantity of the acid?
Because you have described formation of a buffer solution.........
This is seen from the well-known buffer equation, the which we may represent as:
In this ammoniacal scenario, the free base is the uncharged species, the ammonia, and the ammonium acid is charged:
Back in the day, before the advent of electronic calculators, students (and scientists, and engineers, statisticians, and economists) would routinely use log tables to do calculations that a calculator would these days render trivial.

The pH remains relatively constant during the titration of an ammonia solution with a strong acid because ammonia acts as a weak base. It reacts with the strong acid to form its conjugate acid, ammonium ion, which only slightly affects the pH until all the ammonia is consumed.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
