Study Notes

Acid Definitions

Acid: A source of hydrogen ions (H+) when dissolved in water.
Alkali: A source of hydroxide ions (OH-) in a solution, are soluble bases.

Common Acids

Hydrochloric acid (HCl): H+ and Cl- ions
Sulphuric acid (H₂SO₄): H+ and SO₄²⁻ ions
Nitric acid (HNO₃): H+ and NO₃⁻ ions

Salt Formation

Hydrochloric acid and iron ions react to form iron chloride.
Sulphuric acid and magnesium ions react to form magnesium sulphate.
Nitric acid and ammonium ions react to form ammonium nitrate.

Acid + Alkali/Base Reaction

Acid + Alkali/Base → Salt + Water

Acid + Metal Reaction

Acid + Metal → Salt + Hydrogen

Acid + Metal Carbonate Reaction

Acid + Metal Carbonate → Salt + Water + Carbon Dioxide

Ionic Equation for Neutralisation

H⁺ + OH⁻ → H₂O
