In the system solid get transferred into the liquid phase. This transfer result from molecular diffusion as well as eddy diffusion . Because eddy diffusion currents are formed by stirring the system with the help of magnetic stirrer . Due to this concentration of solid in liquid goes on increasing with respect to time .If we provide sufficient time , then this concentration will achieve the value CA which is maximum possible solubility of solid at that temperature.
