Question

why do we need to separate substance from a mixture? class 6​

Answer 1

Answer:

When two or more substances are mixed together they form a mixture. Components of a mixture should be separated because some components may not be useful or may spoil the useful component of the mixture.

Answer 2

$\large\fbox\red{Answer}$

There are three main reasons why we need to separate mixtures.They are:

1) To remove unwanted particles

• A bhel is a mixture of various ingredients like onion, tomato, potato, chillies, etc. Someone who does not like spicy food will remove the chillies to prevent mouth burn. Therefore, separation is necessary to remove the chillies from food.

2) To obtain important substances

• Some substances are more important than others in a mixture.Therefore, these need to be obtained by separation of substances.

3) To obtain pure substances

• A mixture is actually made up of pure substances only. But they get mixed with each other in a mixture. Sometimes the individual pure substances are more important than the mixture. For example, Saltwater is not very important to us. But salt and water individually are very useful to us. Hence, we need to separate both from each other.Thus, separation of substances is necessary to obtain pure substances for domestic purposes, industrial purposes and research work.
