Martin, R. Bruce. 1) When AgBr dissolves, it dissociates like this: 3) There is a 1:1 molar ratio between the AgBr that dissolves and Ag+ that is in solution. Brackets stand for molar concentration. In order to calculate the Kspfor an ionic compound you need the equation for the dissolving process so the equilibrium expression can be written. What is the solubility of AgCl in water if Ksp 1.6 10 10? If Q > Ksp, then BaSO4 will precipitate, but if Q < Ksp, it will not. In a saturated solution, the concentration of the Ba2+(aq) ions is: a. There is a 1:1 ratio between Hg2Br2 and Hg22+, BUT there is a 1:2 ratio between Hg2Br2 and Br. Looking back over my notes that I took over the Khanacademy MCAT prep videos I don't see any examples with this, but doing just a little research you can confirm that the coefficients are incorporated when determining any equilibrium expression (even if it is just 1). Its the equilibrium constant used for equations when a solid substance is dissolving in a liquid/aqueous solution. The Ksp for CaCO3 is 6.0 x10-9. For insoluble substances like silver bromide (AgBr), the molar solubility can be quite small.
