Could u wr ite answer on a paper? 

Barium carbonate (BaCO3) is used in rat poison, bricks, ceramic glazes, and cement. The Ksp of BaCO3 is 2.58 x 10-9.

a) Is BaCO3 acidic, basic, or neutral? How can you tell?

b) What is the molar solubility of BaCO3 in pure water?

c) What is the pH of a saturated BaCO3 solution? The Ka of the bicarbonate ion (HCO3-) is 5.6 x 10-11.

d) If you were to titrate a saturated solution of BaCO3, what would you use as the titrant? Qualitatively sketch the titration curve. Clearly label your axes, the buffer region, and indicate whether the equivalence point is acidic, basic, or neutral.
