What is the solubility product of BaF2?
What is the solubility product of BaF2?
BaF2 (s) ↔ Ba+ (aq) + 2 F- (aq) This reaction shows that for every mole of BaF2 that dissolves, 1 mole of Ba+ and 2 moles of F- are formed. The solubility is equal to the concentration of the Ba ions in solution. solubility = [Ba+] = 7.94 x 10-3 M.
How do you find Ksp of BaF2?
However, since BaF2 is a pure solid in the reaction, it does not have a concentration, so the equilibrium expression simply becomes: Ksp=[Ba2+][F−]2 Since it is only a product of the concentrations of the products, it is called the solubility product constant.

What type of compound is BaF2?
BaF2 B a F 2 , ionic. Barium fluoride is an ionic compound because it is made up of the barium cation (has a +2 charge) and…
What type of bond is BaF2?
Ans. Barium Fluoride is an ionic compound because it is made up of Barium cation, which has a +2 charge and Fluoride anion, which has a -1 charge. The compound has a molecular formula of BaF2. Since there is no shared bonding and only a transfer of ions, it is called an ionic bond.
What is molar solubility?
The solubility (by which we usually mean the molar solubility ) of a solid is expressed as the concentration of the “dissolved solid” in a saturated solution. In the case of a simple 1:1 solid such as AgCl, this would just be the concentration of Ag+ or Cl– in the saturated solution.
How do you calculate solubility?
Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
