1800-102-2727Let’s perform an experiment. Take 100 mL water in a glass and add 1 tablespoon of sugar. Stir the solution till all sugar particles are dissolved. Now add 1 more tablespoon of sugar. Continue this experiment till you find a point where further addition of sugar is not possible.
Can you guess why this happened?
Well, every solution is made up of solute and solvent. There’s a certain threshold of solvent to dissolve the solute. This condition is called equilibrium.
As you reach equilibrium, further addition of sugar is not possible. This state of solution is called saturation, and the solution is called saturated solution. The opposite of saturated solution is unsaturated solution. Unsaturated solution is a solution in which more solute can be dissolved before it attains the saturated state.
On this concept, we will get to know more about unsaturate solutions and their characteristics!
TABLE OF CONTENTS
A solution in which the solute’s concentration is lower than its equilibrium solubility is called an unsaturated solution. When the components of a combination are evenly distributed throughout, the mixture is said to be homogeneous. When the concentrations of dissolved solutes reach the solvent's saturation point, the solution is said to be saturated.
There are three stages of saturation in a solution.
Temperature
When temperature increases it allows more solute to dissolve. As we know, temperature increases the kinetic energy of the particles due to which motion of the particles increases and so do the solubility,
Size of the solute particles
You must have observed that powdered sugars dissolve very quickly as compared to sugar cubes. Smaller the size of the solute particles greater will be the solubility.
Stirring
Stirring the solution increases the net dissolving rate, which minimises concentration build-up at the solvent surface, which would otherwise lead to higher crystallisation in a still solution.
Answer: A
Solution: A saturated solution is one that contains all of the solute that can dissolve in it, given the conditions in which it exists. A saturated sample has more solvent per volume than an unsaturated solution. There are still some undissolved substances in the solution after the solute has been dissolved to the point where it can no longer be dissolved. The solution ultimately sinks to the bottom of the container as the amount of undissolved material increases.
So, option A is the correct answer.
Answer: C
Solution: When the solute concentration is lower than its equilibrium solubility, a solution is said to be unsaturated. In an unsaturated solution, further addition of solute is possible.
So, option C is the correct answer.
Answer: A
Solution: Supersaturated solutions are unstable because the solute is present in them at a concentration higher than the equilibrium solubility value.
So, option A is the correct answer.
Answer: A
Solution:
So, option A is the correct answer.
In an unsaturated solution, can we add more solute?
Smaller amounts of solute than what can dissolve are present in unsaturated solutions, leaving no residue. In an unsaturated solution, the solute would dissolve into the solvent if more were added since the solution has not yet attained saturation.
Are diluted and unsaturated the same term?
A dilute solution is a sort of liquid solution made by adding additional solvent to a concentrated solution, but an unsaturated solution is a type of solution into which we can add more solute. This is the main distinction between diluted and unsaturated solutions.
How can you tell whether a solution is concentrated or diluted?
A solution that contains a significant amount of dissolved solute is said to be concentrated. A solution is said to be dilute if it only contains a little amount of dissolved solute.
What effect can temperature change have on a solution's saturation level?
Because heating a solution enhances its solubility, a saturated solution can be changed into an unsaturated one on heating. An unsaturated solution at one temperature might become saturated at a different temperature since solubility is a temperature-dependent phenomena.
