Question

2. A mixture of salt, sand, oil and water is given ,which of these sequences can be used to separate salt a. Decantation -> Filtration -> Evaporation b. Filtration -> Evaporation -> Condensation c. Filtration -> boiling ->Decantation d. None of the above

Answer 1

Explanation:

decantation and filtration

Answer 2

Answer:

Decantation -> Filtration -> Evaporation method is used to separate salt.

Explanation:

Decantation :

• A method called decantation is used to separate mixtures of immiscible liquid-like suspension.
• For instance, if we leave a bucket of water and mud or sand in it, the insoluble particles will eventually settle at the bottom of the bucket.
• Liquids that cannot mix to produce a solution are said to be immiscible.

Filtration :

• Filtration is the process of removing solid particles from liquid or gaseous fluids by passing the fluid through a filter medium while keeping the solid particles behind.
• The desired product could be either the fluid that has been cleared or the fluid that has had its solid particles removed.

Evaporation

• Evaporation is the process by which a substance transforms from a liquid to a gaseous state below the boiling point.
• In particular, it is how liquid water enters the atmosphere as water vapour throughout the water cycle.

Final answer:

Decantation -> Filtration -> Evaporation is a sequences can be used to separate salt  from a mixture of salt, sand, oil and water.
