Question

7. In caves we sometimes see large structures known as stalactites and stalagmites. These formations are made of crystals of the insoluble compound calcium carbonate, CaCO3(s), also known as limestone. Calcium carbonate forms when dissolved carbon dioxide and calcium ions combine, according to the following equilibrium: CaCO3(s) + 2H+(aq) ? Ca 2+ (aq) + H2O(l) + CO2(g) Use Le Chatelier's Principle to answer the following: a) How would the stalagmites and stalactites be affected if the water in the cave became more acidic? b) How would the hardness of the water [Ca 2+] affect the growth of stalagmites and stalactites?
