REACTIONS OF METALS AND NON-METALS WITH ACIDS

Metals react with acid to produce a salt and hydrogen gas

Metal + dil. Acid--->salt + hydrogen

Eg: hydrochloric acid + zinc --->zinc chloride + hydrogen

Sulphuric acid + zinc--->zinc sulphate + hydrogen

(Hydrogen gas produced will burn with a pop sound when the burning candle is kept near that)

NON METALS generally do not react with acids

Generally, metals react with a base to produce salt and hydrogen (but such reaction is not possible with all metals)

Eg: sodium hydroxide + zinc--->sodium zincate + hydrogen

The reaction of non-metal with base is complex
