Question

Is calcium carbonate soluble in water?

Answer 1

Nope....

Explanation:

`"Calcium carbonate"` is soluble in water to the extent of `13*"ppm"` in water, i.e. `0.013*g*L^-1`...clearly in acidic solution, the carbonate will be decomposed to carbon dioxide and soluble calcium chloride...

`CaCO_3(s) + 2HCl(aq) rarr CaCl_2(s)+H_2O(l) + CO_2(g)uarr`
