Study Notes
Strong Acids
- HCL: Hydrochloric acid
- HNO₃: Nitric acid
- H₂SO₄: Sulphuric acid
- H₃PO₄: Phosphoric acid
- HF: Hydrofluoric acid
Weak Acids
- CH₃COOH: Ethanoic acid
- H₂CO₃: Carbonic acid
Calculating Mass
- m = mass
- M = molar mass
- n = number of moles
- Avogadro's number: 6.02 x 10²³ molecules/mole
pH Scale
- Universal Indicator: Red -> Acid, Green -> Neutral, Blue -> Base
- Litmus Paper: Red -> Acid, Blue -> Base
- PPT/Phenolphthalein: Colorless -> Acid, Pink -> Base
Acids
- An acid is a proton donor
- Releases H⁺ ions in water
Bases
- A base is a proton acceptor
- Releases OH⁻ ions in water
