Answer to Question #253013 in General Chemistry for ali

Question

Question: The reactions for the dissolution of limestone (CaCO3(s)) and for the dissociation of bicarbonate ion (HCO3–) to carbonateion (CO32–) are as follows:

These reactions have reached equilibrium in a solution at pH 9.33 that contains10−2 mol/L CaCO3(s) and10−3.3 mol/L Ca2+.

Answer 1

10^-2/10^-3.3 = 10^1.3

Log 10^1.3= 1.3
