Acids
Basicity of Acids
is the maximum number of hydrogen ions produced by one molecules of the acid when the acid molecule dissociates in water

Uses of acids
manufacture of fertilizers (H2SO4, HNO3)

-
food production (H3PO4, H2CO3, CH3COOH)
Definition
An acid is a substance which dissociates in water/aqueous solution to give hydrogen ions. All acid contain H+ ions.
Pure acid (without water) exists as simple covalent molecules. These acid molecules react with water to produce ions (i.e. acid molecules ionises/dissociates in presence of water)
An acid only exhibits acid properties when dissolved in water. The presence of hydrogen ions cause the acidity.

Properties of acids
-
Chemical
acids react with metals above hydrogen in the reactivity series/metal carbonates/metal hydrogen carbonates/bases (metal oxides/metal hydroxides)
Inorganic Acids
prepared in the laboratory from mineral elements or inorganic matter (HCL, HNO3, H2SO4, H3PO4, H2CO3)
Organic Acids
obtained from plants and animals (CH3COOH, citric acid, ascorbic acid, tartaric acid, lactic acid, lactic acid, tannic acid, formic/methanoic acid)
