How will you separate chalk powder from a mixture of chalk powder and water?
filtration
A mixture of chalk powder and water can be separated using the technique of filtration because: The mixture can easily pass through filter paper. Chalk powder is insoluble in water.
How will you separate a mixture of common salt chalk powder and iron nails?
To separate a mixture of iron filings, chalk powder, and common salt by using a magnet followed by filtration and evaporation. A magnet is moved on a mixture of iron filings, chalk powder and common salt. In the process, iron filings are separated by the magnet.
Which method is used to separate a mixture of salt and camphor?
sublimation
The technique used to separate camphor from salt is sublimation. In this camphor is a sublimable volatile.
How do you separate naphthalene and common salt?
Sublimation is the method of separating naphthalene from common salt. Sublimation involves the conversion of a solid directly into its vapour state without being converted in the liquid state. Naphthalene vapours can be collected after sublimation and the salt remains as residue.
How will you separate a mixture of common salt Sulphur powder and sand?
They can be separated as follows:
- Add water to the mixture.
- Filterate is the solution of Salt and residue contains sulphur and sand.
- Evaporate the filtrate, water will vapourize leaving behind salt.
- To the residue containing sulphur and sand add carbon disulphide, this will dissolve sulphur.
- Filter this solution.
How will you separate a mixture of common salt camphor and iron filling describe the process?
Firstly the magnet is used to remove iron nails. This can be done by handpicking method also, then camphor is separated from the salt by the method of sublimation.
How can we separate a mixture of salt and sand?
Separating Salt and Sand Using Solubility
- Pour the salt and sand mixture into a pan.
- Add water.
- Heat the water until the salt dissolves.
- Remove the pan from heat and allow it to cool until it’s safe to handle.
- Pour the salt water into a separate container.
- Now collect the sand.
Which process will be suitable for separating a mixture of naphthalene powder and chalk powder in the laboratory?
The chalk powder and naphthalene are separated by sublimation. In this process, the mixture of chalk powder and naphthalene is heated. Naphthalene sublimes on heating, and its vapours are condensed over a cold apparatus.
