How will you describe the components of the mixture to be separated using sieving?

The method of separating a mixture by using sieve is called Sieving. Sieving is used to separate those solid mixtures which have components of different sizes. The mixtures having components of different sizes is put in sieve and the sieve is moved back and forth continuously.

Why is it important to use a filter paper when separating the components of the mixture?

Filtration is used to separate a solid from a liquid in which it is suspended. Filtration is also used to separate a substance from a mixture because one is insoluble in the solvent and the other is soluble.

What differences in the properties of the substances allow them to be separated during chromatography?

The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances.

What are properties in matter?

Any characteristic that can be measured, such as an object’s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more, are considered properties of matter.

Why is it important to consider the nature of a mixture to be separated before setting on the separation method?

We need to separate different components of a mixture to separate the useful components from the non-useful or some harmful components.

A	B
What physical property could you use to separate a solution of two liquids?	Boiling point, physical property, distillation
Name three physical properties of a liquid	Boiling poing, Freezing point, color

What properties is used to separate a mixture of oil and water?

Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The mixture of oil and water forms two separate layers because they are completely insoluble in each other. Oil forms the upper layer while water forms lower.

Physical separation techniques are based on the physical properties of the substance. These physical properties can be physical state, magnetic and electrical properties, specific gravity, density, melting point, boiling point and solubility.

What is the physical property that serves to separate substances in a distillation?

The boiling point of a substance determines what component will separate out during the process of fractional distillation. It is used to separate a mixture of two or more miscible liquids for which the difference in boiling points is less than 25 K.

What is the importance of separation of substance define separation of substance?

There are many substance which cannot be used due to presence of impurities in them. Therefore, to obtain a substance in its pure form separation is necessary. By separating impurities, we can increase quality, purity, strength and utility. At the same time, ratio of components of mixture can be estimated.

Determination of chemical properties results in the change of the identity of the substance. Some properties, such as solubility, melting point, boiling point, and density are independent of the amount of substance being examined. These properties are known as intensive properties and are used to identify a substance.
