Question

Title: How to separate homogeneous mixture?
Materials
water (20 ml)
salt (1/4 tsp)
stove or any available used for cookino pot or tin can
Take precautionary steps in handling gas stove.
1. Procedure:
1. Prepare the materials needed
2. Combine water and salt in a pot
3. Stir property until the bits of salt are gone.
4. Put the pot into fire.
5. Observe what happen
Guide Questions:
1. What happens in the water in the pot?
2. What are the components of this solution?
3. What is left in the pot?
4. What process is used to separate salt solution?​

Answer 1

Answer:

1. Water gets evaporate due to the heat or converts in water vapours.

2. Water and salt are the components of this solution.

3. Salt is left in the pot. (reason ans 1)

4. Simple distillation.

Answer 2

Answer:

1. Water gets converted into water vapor by means of evaporation.

2. Salt is the solute and water is the solvent and they are the components of this solution.

3. Salt gets left in the pot.

4. Separation by evaporation.

Explanation:

• Mixtures can be physically separated using methods that separate the components of the mixture using differences in physical properties, such as: Evaporation, Distillation, Filtration and Chromatography. Which separation method is used to separate a mixture depends on what kind of mixture it is (what physical states exist) and the physical properties of the components.
• A mixture consists of two or more substances that may be present in different amounts and can be physically separated using methods that separate the components of a mixture using physical properties such as: Evaporation, Distillation, Filtration and Chromatography.
• Evaporation can be used as a separation method to separate the components of mixtures containing solids dissolved in liquids. Liquids evaporate under high temparature. This often requires heat. When the liquid evaporates completely, only the solid remains.
