Homework Statement
compare the Ks0 values of MnCO3(s) in fresh water (I=0) and in estuarine waters (I=0.08) at 25°C. If each of the waters contained a concentration of CO32- equal to 10-6M and MnCO3(s) controls the Mn solubility, what is the Mn2+ concentration in each water? What is the Mn2+ activity in each water?
Homework Equations
MnCO3 (s) = Mn2+ (aq) + CO32- (aq)
Ks0 = {Mn2+}{CO32-} / {MnCO3 (s)}
Ks0 = yMn2+[Mn2+] yCO32-[CO32-]
