An acid and a base.

Example:

HCl (acid) + NaOH (base) - --> NaCl (salt) + H2O

Salts can also be formed from the reaction between:

Acid and reactive metals:

H2SO4 (acid) + Zn (reactive metal) - --> ZnSO4 (salt) + H2

Acid and metal carbonates (also a type of base):

H2SO4 (acid) + CaCO3 (metal carbonate) - --> CaSO4 (salt) + CO2 + H2O
