Identifying the difference

Postby Jennifer Torres 2L » Wed Dec 05, 2018 6:01 pm

How can you tell whether a slat is acidic or baisc?

We tell whether a salt is acidic or basic based on whether the pH is changed by the addition of H+ or OH-; a salt is acidic if it forms H30+ when reacting with water in solution and it is basic if it forms OH- when reacting with water in solution.

If they increase the H+ or H3O+ concentration in the solution, it is an acid. If they increase the OH- concentration in the solution, it is a base.

Another thing to note is that the conjugate bases of strong acids do not affect the pH of the water, for instance Cl- ion doesn't raise the pH despite it being a conjugate base.
