sand and water?

a. Simple distillation

b. Crystallization

c. Fractional distillation

d. Filtration​

Answer 1

Answer:

I think the answer is filtration maybe?

Answer 2

The correct method for separating pure water, in this case, is an option a: Simple distillation.

• The solvent is evaporated and condensed in a connecting chamber called a condenser in the simple distillation method.
• This condensed liquid is in its pure form and is correct in a beaker.
• A mixture of salt, sand and water is to be separated.
• Salt and sand both are solid in nature.
• Therefore salt and sand will not evaporate from the flask containing the mixture.
• Water being liquid will start evaporating once it reaches its boiling point. It then undergoes condensation to liquid. This liquid obtained is pure water.
• Filtration is not helpful because the mixture of salt and water is not separated by this.
• Crystallisation and fractional distillation methods are not used here.
• Hence, option a is correct.
