Calcium carbonate is the principal mineral component of limestone. Its chemical and physical properties lie behind the modern-day uses of limestone as well as the unique limestone landscapes of the countryside. The principal mineral component of limestone is a crystalline form of calcium carbonate known as calcite. Although calcite crystals belong to the trigonal crystal system, shown below, a wide variety of crystal shapes are found. Single calcite crystals display an optical property called birefringence double refraction. This strong birefringence causes objects viewed through a clear piece of calcite to appear doubled. Another mineral form of calcium carbonate is called aragonite.

When hydrochloric acid reacts with any carbonates/hydrogen carbonates the products formed are metal chloride, water and carbon dioxide.

This study aimed to investigate the ability of different concentrations of calcium carbonate CaCO3 suspensions to control enamel surface loss. Seventy-five enamel slabs were embedded, ground and polished in a pneumatic grinder-polisher machine. The samples were then exposed to suspensions containing 0. Artificial saliva was used as control. The samples were subjected to a total of five erosive cycles followed by treatment with CaCO3 suspension. The lower concentrated suspensions were incapable of significantly reducing enamel surface loss. Rinsing with 0.

To balance chemical equations we need to look at each element individually on both sides of the equation. There is one Calcium atom on the left and one Calcium atom on the right so this is balanced. There is 1 hydrogen atom on the left but 2 on the right so this is unbalanced. Therefore we need to balance it by using 2 molecules of HCl:. Lastly we need to check that the chlorine is balanced, and it is as we can see there are now 2 on each side. Therefore this is now a balanced equation.
