changes. Consider the equilibrium represented by equation 1.10. This, being dynamic equilibrium, must follow Le Chateliers Principle. In general, if in a nearly saturated solution, the dissolution process is endothermic (Dsol H > 0), the solubility should increase with rise in temperature and if it is exothermic (Dsol H < 0) the solubility should decrease. These trends are also observed experimentally. Effect of pressure Pressure does not have any significant effect on solubility of solids in liquids. It is so because solids and liquids are highly incompressible and practically remain unaffected by changes in pressure.
