Neutralisation ReactionsMetal Oxides - BaseMetal oxides react with acids to form salts and water. E.g. copper oxide + sulphuric acid -> copper sulphate + waterCuO + H2SO4 -> CuSO4 + H20Generally speaking, acid + base -> salt + waterMetal + AcidMetal + acid -> salt + hydrogenAKA M.A.S.H (Metal + Acid -> Salt + Hydrogen)For example, magnesium + hydrochloric acid → magnesium chloride + hydrogenMg + 2HCl → MgCl2 + H2zinc + sulphuric acid → zinc sulfate + hydrogenZn + H2SO4 → ZnSO4 + H2Reactions with waterMetal + water -> metal hydroxide + hydrogene.g Potassium + water -> Potassium Hydroxide + hydrogenDisplacement ReactionsWhen one metal is more reactive than the other, it displaces it. For example, aluminium + iron oxide -> aluminium oxide + ironEquations with carbon dioxideCarbon dioxide is produced whenever an acid reacts with a carbonate. A metal with carbonate has carbon dioxide.calcium carbonate + hydrochloric acid → calcium chloride + water + carbon dioxideCaCO3 + 2HCl → CaCl2 + H20 + CO2
