How will you separate a mixture of common salt, chalk powder and powdered camphor? Explain.​

Separating camphor​

• When this mixture is heated, camphor sublimes and forms camphor vapours and gets separated from the mixture.

Separating chalk powder​

• When the resulting mixture containing common salt and chalk powder are added to water. ​
• As common salt dissolves in water so it forms a homogeneous mixture with water. ​
• The chalk powder being insoluble forms a heterogenous mixture with water.​
• So, the chalk powder can be separated from the resulting mixture by passing through a filter paper.​ ​

Obtaining salt ​

• Common salt can be separated from the obtained filtrate by evaporation of water. ​
