(b) Acid + Base → Salt + Water
(c) Acid + Carbonate → Salt + Water + Carbon dioxide
or bicarbonate
(d) Acid + Sulphite or bisulphite → Salt + Water + Sulphur dioxide
(e) Acid + Sulphide → Salt + Hydrogen Sulphide
Metals react with mineral acids to form Salt + Hydrogen.
Dilute acids like hydrochloric acid (HCl), sulphuric acid H2SO4 react with certain active metals to evolve hydrogen gas and form their metallic salts.
