Explain the equilibrium involving the dissolution of a solid in a liquid.

(N/A) When a solid solute is added to a liquid solvent,it dissolves until the solution becomes saturated. At this point,a dynamic equilibrium is established between the undissolved solid and the dissolved solute.
$Solute \text{ (solid)} \rightleftharpoons Solute \text{ (in solution)}$
At equilibrium,the rate of dissolution of the solid equals the rate of crystallization of the solute from the solution. The concentration of the solute in the solution remains constant at a given temperature.
