Question

How can we separate salt dissolved in salty water?

Answer 1

When we boil water, salt has a different boiling point from water.
The boil point for salt might be higher than boiling point of water.
Salt cannot boil at the boiling point of water.
At their different state, we can separate one from the other then.
It shall sink and dissolve in water with its low density.

Flour may dissolve in water when we mix them with anything or shake it with a tool or instrument now.

Answer 2

Answer:
≻By Simple distillation.

⋆For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container.
