Question

salt dissolves in water. but as salt is constantly added to the water, at some point salt appears at the bottom of the vessel. why does this happen?​

Answer 1

Answer:

Though salt is soluble in water, adding salt constantly can result in deposition of salt in the bottom of the vessel . This is b'coz salt occupies space between the molecules of water hence dissolves. But after adding in a large amount it Settles down as there is no space btw molucules.

Answer 2

Answer:

Saturation refers to the level where none of the water molecules are available to bind with the ions of the particular solute, here sodium chloride. Thus, the excess amount of the solute gets deposited at the bottom of the vessel.
