To 1.00 l of water was added 2.00 g of solid barium carbonate, baco3. after stirring, it was found that the solid did not dissolve completely.
a) calculate which mass of baco3 has dissolved.
b) check that at ph = 4 the added mass of barium carbonate would dissolve completely.
data: pkps (baco3) = 8.3; pka1 (h2co3) = 6.35; pka2 (h2co3) = 10.33; mr(ba) = 137.3; mr(c) = 12.0; mr(o) = 16.0
