Calcite is an impure form of Calcium Carbonate (CaCO3). Vinegar is the every=day name for the carboxylic acid , Ethanoic (Acetic) Acid (CH3COOH).

Remember for all acid/carbonate reactions.

Acid + Carbonate = Salt + Water + Carbon Dioxide((g) - bubbles).

Hence 2CH3COOH + CaCO3 = Ca(CH3COO)2(aq) + H2O(l) + CO2(g)

The Effervescence (Bubbles)- you see is the carbon dioxide (CO2) being liberated.

Calcite is CaCO3...Calcium Carbonate, Carbonates always have a chemical reaction with acids. The vinegar is a weak acid but still reacts, and CO2 gas is given off in the bubbles seen.

What is the Calcite test?

Answerfrom windows.ucar.edu (see link to the left): Everyone's favorite way of identifying calcite is the acid test. When you place a drop of weak acid, such as vinegar, on calcite, it will bubble. This happens because a reaction causes a little bit of the calcite to break down, releasing carbon dioxide gas, making the bubbles.and also by hcl test
