A soluteis any substance which can be either solid or liquid or gas dissolved in a solvent. Case II: When , then solution is saturated in which no more solute can be dissolved but no ppt. Dr.S.SURESH So let's plug that in, so this is equal to 2.2 times 10 to the negative 20 and this is equal to the concentration of copper II plus ions at equilibrium which is x. Calculate the solubility product. Solubility Product (Ksp) = [products]x/[reactants]y but..... reactants are in solid form, so Ksp=[products]x i.e. –The equilibrium constant for this process is called the solubility product constant, K sp. Now it is important for you to understand that it does not change the K_sp . Suppose that 555 mL of a 0.0022 M solution of TlNO 3  K sp  Ag  -7 2   Br   5.7 x 10   3.3 x 10-13 3 But [BA] = constant. And so now we can solve for Ksp because we know the equilibrium Presentation Summary : Chapter 17: SOLUBILITY: K sp. Complete the statement. Hence the temperature at which a solubility product is measured should always be stated. Solubility Product (Ksp) = [products]x/ [reactants]y but..... reactants are in solid form, so Ksp= [products]x Ksp= [A3+]2 [B2–]3 i.e. Solubility is a major challenge for formulation scientist.
