Question

Technique by which Mercury and water can be separated.
Trohnique bwhich water and sand can be senarated​

Answer 1

.Answer:

DECANTATION

1.Explanation:

Mercury and water are separated by decantation by using separating funnel as the separation of two immiscible liquids by a separating funnel depends on the difference in their densities. Mercury is heavier than water therefore, forms the lower layer and separated from water.

2.EXPLANATION

In a mixture of sand and water, the heavier sand particles settle down at the bottom and the water can be separated by decantation. Filtration can be used to separate components of a mixture of an insoluble solid and a liquid.
