Équilibre de dissolution : introduction

In this video, we explain the difference between the solubility product Ks (which is the equilibrium dissolution constant) and solubility, in g/L or mol/L (which is the amount of solute that can dissolve, at equilibrium, in 1 L of water). We also explain why, when comparing the solubility of two salts, solubilities are the basis.
