Stalactites and stalagmites in eaves are made of iStalactites and stalagmites in eaves are made of insoluble compound calcium carbonate, CaCO_3(s). It forms when dissolved carbon dioxide and calcium ions combine Ca^2+ (aq) + H_2O_(l) + CO_2_(g) CaCO_3(s) + 2 H^+_(aq) a) How would the stalagmites and stalactites be affected if the water in the cave became more acidic? Explain [A, 2m] b) How would the hardness of the water (more Ca^2+ (aq))affect the growth of stalagmites and stalactites? ExplainShow transcribed image text
