What ions to alkalines form
OH-
Acid+…—>salt+…
Base
Water
H+ + OH- –>
H2O
The products of neutralisation are

Hydrochloric acids produce what salt
Chloride salts
Nitric acids produce nitrate salts when
Neutralised

Water
Acid + metal hydroxide —-> …. + water
Salt
Ammonia is neutralised with nitric acid to make
Ammonium nitrate
What is ammonium nitrate used as
A fertiliser
Soluble salts are made by using…
A metal or insoluable base
Describe the method for making soluble salts
Add the metal (oxide/hydroxide) to the acid the solid will dissolve. When the acid has been neutralised all the excess solid will sink to the bottom. Evaporate the water add the crystals will be left
