Carbonic acid is the chemical compoond wi the formula H2CO3 (equivalently OC(OH)2). It is an aa a name whiles gien tae solutions o carbon dioxide in watter (carbonatit watter), acause sic solutions contain smaa amoonts o H2CO3. Carbonic acid, which is a weak acid, furms twa kinds o sauts, the carbonates an the bicarbonates. In geology, Carbonic acid causes limestane tae dissolve producin calcium bicarbonate which leads tae mony limestone featurs sic as stalactites an stalagmites.
