Chemistry: pH of salt solutions

The pH of a salt solution is determined by the relative strength of its ​conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3).

Chemistry

Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

Acid-base equilibria

In this tutorial, we will learn how the strength of an acid or base is related to the equilibrium reaction that is happening in our solution. We will also see what happens when we mix solutions of acids and bases in neutralization reactions.
