Common Acids and Bases
Frequently encountered acids and bases with formulas.
Common laboratory and household acids and bases with formulas, strength classification and whether they are acidic or basic: hydrochloric, sulfuric, nitric and acetic acid, sodium and potassium hydroxide and ammonia, plus phosphoric, carbonic, citric, hydrofluoric and other acids and several additional bases.
Use it when
- You need the formula and general strength of a common acid or base.
- You are building an acid-base example or a safety table.
Watch out for
- Strength describes how completely a substance dissociates, not how hazardous it is: hydrofluoric acid is a weak acid but extremely dangerous.
- Some bases, such as calcium hydroxide, are strong but only sparingly soluble.
