Question

give examples of saturated solution, unsaturated solution and supersaturated solution.

Answer 1

Answer:

Examples of Unsaturated Solutions:

• Adding a spoonful of sugar to a cup of hot coffee produces an unsaturated sugar solution.

• Vinegar is an unsaturated solution of acetic acid in water.

• Mist is an unsaturated (but close to saturated) solution of water vapor in air.

• 0.01 M HCl is an unsaturated solution of hydrochloric acid in water.

Example of Saturated Solutions:

• A soda is a saturated solution of carbon dioxide in water. This is why, when the pressure is released, carbon dioxide gas forms bubbles.

• Adding chocolate powder to milk so that it stops dissolving forms a saturated solution.

• Salt can be added to melted butter or oil to the point where the salt grains stop dissolving, forming a saturated solution.

• If you add enough sugar to your coffee or tea, you can form a saturated solution. You'll know you've reached the saturation point when the sugar stops dissolving. Hot tea or coffee allows much more sugar to be dissolved than you can add to a cold beverage.

• Sugar can be added to vinegar to form a saturated solution.

Example of Supersaturated Solutions:

• 40g NaCl in 100ml H2O. The additional 4.0g NaCl remains undissolved.

Answer 2

Answer:

Unsaturated solution: This is a solution in which more solute can be dissolved at a given temperature. In this case, solute can be added until the solution reaches the saturation point.

E.g. 5 g or 10 g or 20 g of NaCl in 100 g of water.

2. Saturated Solution: A solution in which no more solute can be dissolved in a certain amount of solvent at a given temperature is called a saturated solution.

E.g. 36 g of NaCl in 100 g of water at room temperature forms a saturated solution.

3. Supersaturated solution: A solution that has more solute than a saturated solution at a given temperature is called a supersaturated solution.

E.g. When you open the can, the pressure of the carbon dioxide drops drastically, reducing the solubility of the carbon dioxide. The resulting soda is then a supersaturated solution that releases excess carbon dioxide as bubbles over time.
