True or false?
(a) A mixture of milk and water can be separated by filtration.
(b) A mixture of powdered salt and sugar can be separated by the process of winnowing.
(c) Separation of sugar from tea can be done with filtration.
(d) Grain and husk can be separated through the process of decantation.
(a) False
Filtration is used for the separation of solid components of the mixture from the liquid. But here both the components are liquids.
(b) False
Winnowing is used to separate heavier particles from the lighter particles which can be blown away by the wind. But here both sand and sugar are heavy particles.
(c) False
The separation of sugar from tea can not be done with filtration because sugar is soluble in water.
(d) False
Decantation is used to separate insoluble solid components from the liquid component.
[Extra information: Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered by using filter paper. The sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate ).
Sedimentation - Sedimentation is the process in which heavier particles of an insoluble solid settle down in a liquid. It is a process by which one can separate mixtures of substances.
Eg: we can remove sand from water through the process of sedimentation.
Decantation is the process of pouring out the liquid without disturbing the sediment.
Eg: sand and water]
