Best Answer: Minerals vary widely in their chemical response to groundwater. Calcite, for example, is soluble in a weak acid such as H2CO3 - carbonic acid. Thus, limestone which consists primarily of calcite (CaCO3) is vulnerable to chemical attack by groundwater.Carbonic acid can form by a reaction between water and carbon dioxide.As rainwater, already slightly acidic (pH~6), passes through the atmosphere and the soil layer, it mixes with carbon dioxide and forms carbonic acid.arbonic acid can form by a reaction between water and carbon dioxide.
