What does each ending of the word mean

ate=oxygen is present

ide=remains normal (no O2)

What is the definition of an acid

Contains H+ ions (proton donor)

What is the definition of a strong acid

Fully ionises in water solution

What is the definition of a weak acid

Partially ionises in solution

What is a base

a proton acceptor

what is an alkali

Soluble base (donate OH- ions) in solution

What is a salt

Substance formed when the H+ ion of an acid is replaced by a metal ion of ammonium atom

List the 5 equations necessary for salts

Metal+acid→salt+hydrogen

Metal oxide+acid→salt+water

Metal hydroxide+acid→salt+water

Metal carbonate+acid→salt+water+carbon dioxide

Ammonia+acid→salt
