Chemistry - Reactivity Series, Oxides, Acid & Base Reactions

Acid + Metal

Acid + metal → Salt + Hydrogen Gas

Acid + Carbonate

Acid + Carbonate/Hydrogen Carbonate → Salt + Carbon dioxide + Water

Neutralisation

Neutralisation = Acid + Base → Salt + Water

Base + Metal

Base + Metal → Salt + Hydrogen gas

Ammonium Salt + Base

Ammonium Salt + Base → Ammonia gas + Salt + Water (when heated)

Acidic Oxides

All non metal oxides except CO, NO, H2O

Dissolve in water to form acidic solution

Reacts with base to form salt and water

Basic Oxides

All metal oxides except ZnO, Al2O3, lead oxides

React with acid to form salt and water

Most are insoluble, soluble ones form alkaline solutions

Amphoteric Oxide

Zinc oxides, aluminum oxide, lead oxide

React with both acids and bases

Neutral Oxide

Carbon monoxide, Nitric oxide, Water

Neither basic nor acidic

Soluble

Nitrates, NO₃^-

Halides, Cl^- ,Br^- (except Ag+ and Pb2+)

Sulfates, SO₄^2-(except Ca2+,Pb2+ and Ba2+)

Alkali metals

Ammonium salts

Insoluble

Phosphates, PO₄^3- (except alkali metals and ammonium salts)
Hydroxides, OH^- (except alkali metals)
Oxides, O^2- (except alkali metals)
Carbonates, CO₃^2- (except alkali metals and ammonium salts)
