Neutralisation Reactions

Like acids and alkalis, acids and metal oxides and hyrdoxides make salt and water

Acid + Metal Oxide -----> Salt + Water

Acid + Metal Hydroxide -----> Salt + Water

The metal and acid decide the name of the salt:

Zinc oxide + Sulfuric Acid ----> Zinc Sulfate + Water

Calcium Hydroxide + Sulfuric Acid -----> Calcium Sulfate + Water

While metal carbonates introduce another product after the reaction which is carbon dioxide

Metal Carbonate + Acid  ----> Salt + Water + Carbon Dioxide

Calium Carbonate + Hydrochloric Acid ----> Calcium Chloride + Water + Carbon Dioxide

An acid and alkali create a neutral product and the reaction between the two is known as a neutralisation reaction. This means the product should have a pH of 7

Acid + alkai -----> Water + Salt

H+(acid ion) + OH-(alkali ion) -----> H20(water)

An Acid + A metal makes a salt + hydrogen

Acid + Metal -----> Salt + Hydrogen

The more reactive a metal the faster the rate of reaction.

The rate of reaction in a dilute acid is indicated by the rate of hydrogen bubbles

Hydrogen can be confirmed with the burning splint test giving a 'Squeaky pop'

Hydrochloric acid will always make chloride salts:

Magnesium chloride (MgCl2)

Zinc chloride (ZnCl2)

Aluminum chloride(AlCl3)

Sulfuric Acid will always make sulfate acids:

Magnesium sulfate (MgSO4)

Zinc sulfate(ZnSO4)

Aluminum sulfate(Al(SO4)3)
