A continuation about Chemical Reactions. This one is about the reaction of Metal Carbonates with Acids, and again, is easy to understand.
A Metal Carbonate is a metal combined with Carbon and Oxygen, e.g. Copper Carbonate, Calcium Carbonate, etc. When a metal carbonate reacts with acid, Carbon Dioxide gas is released and a salt is formed.
Different acids react to form different salts:
Hydrochloric Acid ? Chloride
Sulphuric Acid ? Sulphate
Nitric Acid ? Nitrate
The general equation for the reaction of a Metal Carbonate with Acid is
“Metal Carbonate + Acid ? Salt + Carbon Dioxide + Water”
Copper Carbonate + Sulphuric Acid ? Copper Sulphate + Carbon Dioxide + Water
Zinc Carbonate + Hydrochloric Acid ? Zinc Chloride + Carbon Dioxide + Water
Potassium Chloride + Nitric Acid ? Potassium Nitrate + Carbon Dioxide + Water
