The value of the constant identifies the degree of which the compound can dissociate in water. Im still confused regarding the formula to use and when to use the coefficients For example if you have the 2011 destroyer, in question 86 the answer uses the 2Ca as (2x) ^2 but in question 136 he decides to " neglect " the value since ksp is so small, but in question 86 the ksp is also small. Ksp>10^10 (just a approximate value) For this the solubility will be AB4>AB3>AB2>AB because solubility will be related to Ksp as [(ks)^k]*s =Ksp, where k=1,2,3,4. 62x10^-2 M. 1: PbCl2-->Pb+2 + 2Cl- (generally show the dissociation of PbCl2 in an acid solution that's capable) use this 2Cl- since this is essentially the Anion(electron being donated by the base PbCl2 by Lewis Acid rule) 2. Exercise 13 Calculating Ksp from Solubility II. For example the higher the Ksp the more soluble the compound is.
