Filtration
FILTRATION: Process by which solids are separated from a liquid mixture
If we filter a mixture of solid and liquid:
a. The liquid and anything soluble (able to dissolve) in the
water will flow through the small holes of the filter.
Salt is soluble (dissolves in water), so it will flow through the filter.
During filtration, the mixture just gets filtered.
b. The solids (that are not soluble) will not flow through the filter. Sand is not soluble and will not flow through the filter.
So if we filter a mixture of sand and salt water:
a. The salt and water will flow through the filter. b. The sand will not flow through the filter.
