Question

write difference between saturated and unsaturated solution IN tabular form

Answer 1

Degree of saturation refers to the amount of solute dissolved in a solvent at a certain temperature. If the solvent could dissolve more solute than is present, the solution is unsaturated. If the solvent has dissolved the maximum amount of solute possible (at that temperature), the solution is saturated. If the solvent has more solute than the maximum that can be dissolved at that temperature, the solution is supersaturated. You might wonder how that can happen. If the solvent is heated and a saturated solution is made and then the solution is cooled.
Brine is made by adding salt to pure water with constant stirring. When all has dissolved, add a little more until no more dissolves, leaving a little pile of undissolved solid salt at the bottom of the container. That slightly turbid liquid is a SATURATED aqueous salt solution.

If that mixture is warmed slowly, with stirring, the undissolved salt goes into solution. If then the warm solution is filtered and allowed to stand undisturbed, it will cool slowly to room temperature. At this point, the solution is called SUPERSATURATED, because the salt content exceeds the book value for the solubility of salt in water. At any time, it may begin to crystallize out, with crystals growing on the walls of the container. If nothing happens, you can induce crystallization by scratching the inside walls of the container. Crystal formation will proceed along the scratch mark

I’ve never heard of an UNSATURATED solution, but you can prepare a salt solution of any concentration you wish, as long as it’s below the upper solubility limit for salt at room temperature.

In an unsaturated solution you can always dissolve a little more of the solute.

In contrast to this, a saturated solution will not tolerate the addition of any more of the solute: The extra quantity will remain in the non liquid phase (solid or gas), regardless of how much you stir.

Originally Answered: What is the difference between saturated and unsaturated solution?
An unsaturated solution is one in which additional solute can still be dissolved without heating. As more and more solute dissolves into the solution, a state is eventually reached where it seems that additional solute can no longer be dissolved, creating a saturated solution.

However, this does not mean that no solute continues to dissolve into the solution. Rather, an equilibrium is established where as more solute dissolves into the solution, an equal amount of solute is precipitated out of the solution. Hence no matter how much additional solute is added to the solution and how vigorously one stirs, the concentration of the solution would not increase unless heat is applied.
