There are many different types of reactions which include

  • Corrosion of metals. Eg. The rusting of iron

Iron + water + oxygen  rust

4 Fe(s) + 6 H2O(l) + 3 O2(g) 4 Fe(OH)3(s)

Iron(III) hydroxide, Fe(OH)3 then dehydrates to produce Fe2O3.nH2O(s) or rust

  • Combustion: Eg. The burning of fossil fuels

Methane + oxygen Carbon dioxide + water

CH4(g) + O2(g)  CO2(g) + 2H2O(l)

  • Acid and base : Eg. Hydrochloric acid and sodium hydroxide.

Hydrochloric acid + sodium hydroxide  Sodium chloride + water

HCl(aq) + NaOH(aq)  NaCl(aq) + H2O(l)

  • Acid and carbonate: Eg. Vinegar and bicarb of soda
  • Acid and active metal: This type of reaction is also called a single displacement reaction. Eg. The dissolving of magnesium ribbon in hydrochloric acid.
  • Precipitation: This type of reaction is also called a double displacement reaction. Eg. Mixing colorless lead nitrate and potassium iodide to yellow produce lead iodide.
  • Decomposition: Eg. Hydrogen peroxide being broken down into water and oxygen
  • Synthesis: Eg. The burning of magnesium in air to produce magnesium oxide.
  • Displacement: Eg. The production of copper wool by from steel wool being placed into a solution of copper sulphate.
  • Redox (Reduction/ Oxidation): Eg. Making a battery.
  • Condensation: Eg. Glucose and Fructose producing sucrose
  • Dehydration: Eg. Adding concentrated sulphuric acid to sugar
  • Substitution: Eg. Bromine reacting with octane in the presence of UV light.
  • Addition: Eg. Adding bromine to cyclohexene
  • Polymerisation: Eg. making Nylon, polyethylene
  • Fermentation: Eg. The making of wine
  • Exothermic: Eg. The thermite reaction is used to weld rail tracks together. The reaction is so hot molten iron is produced!
  • Endothermic: Eg. An ice pack. Mix the contents inside the packet and the mixture becomes cold
