What's Ksp for CaCO3?
What's (H3O^+)?
The chief compound in marble is CaCO3. However, marble is readily attacked by acids.
a) Determine the molar solubility of marble (that is, [Ca2+] in a saturated solution).
b) Determine the equilibrium constant for the overall reaction that occurs when marble reacts with acid.
CaCO3 (s) + H3O+ ↔ Ca2+ (aq) + HCO3- (aq) + H2O (l)
