electroloytes
form ions when dissolved in water and produce solutions that conduct electricity
strong electrolyte
dissociates completely in a solvent
weak electrolyte
dissociates only partly in a solvent
solubility
the dissolving ability of a salt in a fixed amount of H2O
molar solubility
number of moles of solute in 1L of saturated solution
common ion effect
adding another source of ions improves the precipitations (decreases the solubility) of insoluble species
activity
effective concentration of an ion, taking into account the effects of its ionic atmosphere
as concentration increases, molar solubility
increases
as concentration increases, ionic strength
increases
when ionic strength increases, the activity coefficient
decreases
Ksp
activity based solubility product
K’sp
concentration based solubility product
