Separating Mixtures through crystallization.

Separating Mixtures through Crystallization.

Requirements.

1. Water in a beaker.

2. Some salt.

3. A heat source.

4. Filter paper.

5. Glass bowl.

Procedure.

1. Place 50ml water in a beaker.

2. Add salt to it and stir.

3. Heat the solution.

4. Continue adding salt to the solution.

5. After some time, there will be a point at which no more salt can dissolve in water. This

6. stage is called saturation point and the solution in known as a saturated solution.

7. Therefore, a saturated solution is a solution that can no longer dissolve any more

8. solute.

9. Filter the salt with the help of a filter paper.

10. Collect the filtrate in a glass bowl and cool it.

Record your observation.

Observation and explanation.

1. In the experiment, some fine crystals are formed in the bowl.

2. Crystallization is a separation method used to separate a solid that has dissolved in a

3. liquid.

4. A solid, for example salt(solute), is dissolved in a liquid, for example water, (solvent)

5. making a solution.

6. The solute is added to the solvent until no more of it dissolved. This makes the solution

7. saturated.

8. As the solvent evaporates from the saturated solution, the solid will come out of the

9. solution and crystals will start to form.

10.  Collect the crystals and allow them to dry.
