A problem from Chem.,Q.A.:
We are asked to write the mass balanced expressions for a solution saturated in MgCO3. I came up with 3 eq. equations:
Mg2CO3 in eq. with Mg2+ + CO32-
CO32- + H2O in eq. with HCO31- + OH1-
HCO31- + H2O in eq. with H2CO3 + OH1-
So I have, neglecting the dissociation of water, hydroxide conc. equaling the sum of hydrogen carbonate and carbonate conc. equaling Magnesium ion conc. Is that correct?
