The chief compound in marble is CaCO3. However, marble isreadily attacked by acids.
[Ca2+] in normal rainwater of pH 5.0 = 0.024 M
a) Determine the molar solubility of marble (that is, [Ca2+] ina saturated solution).
b) Determine the equilibrium constant for the overall reactionthat occurs when marble reacts with acid
CaCO3 (s) + H3O+ ↔ Ca2+ (aq) + HCO3- (aq) + H2O (l)
My problem is that I have been given no more information otherthan what is written above. I'm not sure how to go about solving itwith this amount of information.
