Key Stage 3

Meaning

A Metal Carbonate is a basic metal compound made of one or more Metal atoms and one or more Carbonates that have the formula CO₃

About Metal Carbonates

Metal Carbonates have a pH greater than 7

Some Metal Carbonates are insoluble solids.

Some Metal Carbonates dissolve in water to make Metal Hydroxides which are alkalis.
