Solubility equilibrium Factors affecting
solubility
- solubility equilibrium: in an - solubility of a salt is lower
aqueous solution, in a solution containing
sparingly soluble salt common ion
exists in equilibrium w/ - b/c common ion
component ions suppresses ionization of
- ksp: solubility product weak acids and bases
constant that governs - can understand more by
equilibrium of these applying le chatelier
sparingly soluble salts principle
- for dissolution of ionic - when anion of slightly
cpmd in h2o soluble salt is conjugate
- molar solubility: solubility base of weak acid or base oh-,
in units of mol/l. salt becomes more soluble
- larger ksp doesnt always in acidic solution
mean higher solubility. - b/c when ph is more acidic,

same stoichiometric h3o+. H3o+ can react with
amounts, then higher oh-, making solution more
ksp means higher soluble
