Acid + Carbonate

Carbonate is found in lots of rock-forming minerals as well as in egg shells, corals and oyster shells. It is a major component of limestone, and of marble. 
What happens when carbonate minerals, shells, corals and marble statues meet acids?  
AUS-e-TUTE has just added a new tutorial, game, test and exam to help you write word equations for carbonate and acid chemical reactions. AUS-e-TUTE members should log-in to use these new resources.

A "free-to-view" tutorial is currently available to non-members at
