Study Notes

Acids and Bases

A base is a substance that accepts protons (H+ ions) or donates electrons.

Characteristics of Acids and Bases

An acid is a substance that donates protons (H+ ions) or accepts electrons.
Acids have a tendency to release H+ ions in a solution.

Reaction of Acids and Bases

When an acid reacts with a base, it forms a salt and water, releasing heat in the process (neutralization reaction).

Salts

In an aqueous solution, a salt is a substance that dissociates into ions, but does not affect the pH of the solution.
Salts are formed by the reaction of an acid and a base.

Ionizable Compounds

An ionizable compound is a substance that can release ions in a solution, such as acids, bases, and salts.
