Copper (II)Oxide

Lead (II)oxide

Sodium hydroxide

Calcium hydroxide

This is because it is thehydroxide ions that give alkalisits properties

Acid + Alkali => Salt + Water

E.g. Sodium Hydroxide +Sulfuric Acid =>Sodium Sulfate+ Water

Test for Ammonia gas: If a colourless,pungent gas that turns damp red litmuspaper blue is produced, the gas is ammonia.

Sodium hydroxide + Copper(II)sulfate=> sodium sulfate +Copper(II) hydroxide

When a reactive metal, e.g. magnesium, isadded to an inorganic acid like hydrochloricacid or sulfuric acid, effervescense will beobserved.

The reactive metal willdissolve and the reactionwill give out heat.

The bubbles of gasproduced containhydrogen gas.

Hydrogen gas can be tested byinserting a lighted splint into a testtube. If the gas is hydrogen, thesplint will extinguish with a 'pop'sound.

Unreactive metals likecopper and silver will notreact with acids

When a carbonate compound, e.g. calciumcarbonate, is added to an inorganic acid likehydrochloric acid or sulfuric acid,effervescence will be observed.

The bubbles of gasproduced containcarbon dioxide gas.

Carbon dioxide can be tested for bybubbling the gas into calcium hydroxidesolution, also known as limewater. If thegas is carbon dioxide, a white precipitatewill be observed in the calciumhydroxide solution.

Types of oxides

This is because the hydrogen ions are able tomove about freely in the acid and thus cancarry the electric charge
