React to form water, carbon dioxide, and a corresponding calcium salt.

The reaction between carbonate minerals and hydrochloric acid can be represented by the following equation:

CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)

In this reaction, calcium carbonate (CaCO3) reacts with hydrochloric acid (HCl) to form calcium chloride (CaCl2), water (H2O), and carbon dioxide (CO2). The carbon dioxide gas escapes from the solution as bubbles, causing effervescence.
