Calculate the molar solubility of barium fluoride, BaF2, in water at 25oC. The Ksp at 25oC is 1.0 x 10-6. Since "x" represents the molarity of the Ba+2 ion, and we get one mole of barium ions for each mole of barium fluoride that dissolves.

barium hydroxide octahydrate (Ba(OH)2.8H2O) and ammonium thiocyanate (NH4SCN) are mixed in a beaker, which is then placed on a few drops of water on a small board.
