The solubility rules say no, since any carbonates are insoluble except for the "always soluble" cations. However I had a question on Kaplan, and it stated that CaCO3 can interact w/ HCl and that it was actually a salt of a weak acid. Because of that it is apparently soluble, but doesn't that go agaisnt the rules? Its my undedrstanding that only CaO and Ca(NO3)2 are soluble no?

those rules are not concrete, but as for the DAT... CaCO3 is not soluble in water. i highly doubt test makers will put a "u shoulda known that obscure fact in gchem" on the test. just stick to the basic rules n ull be set

It's chalk...I don't think it would dissolve. But we do know HCO3 does, flows in the blood.
