Fine chemicals - Chemicals made by industry in smaller quantities than bulk chemicals. Fine chemicals are used in products such as food additives, medicines and pesticides.
Bulk Chemicals - Chemicals made by industry on a scale of thousands or millions of tonnes per year, e.g. sulphuric acid and chlorine.

H+(aq) + OH-(aq) = H20 (l)
