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.
