WhatsApp: +86 18203695377Saturation and Dissolution. A solute that normally dissolves in water, like sugar or salt, won't continue to dissolve once it reaches saturation point. This is when the maximum amount of the solute has been dissolved into the water. The solution is at equilibrium, as the rate of dissolution and the rate of reforming the solid solute are equal.
