Question


Which among the following methods can be used to separate heterogeneous mixtures into their respective constituents?


Options:
A .   Handpicking
B .   Filtration
C .   Sieving
D .   Distillation
Answer: Option A
:
A, B, and C
A heterogenous mixture contains physically distinct parts and have non-uniform composition.

  • Sieving is typically used for separating particles by size through a mesh as we notice near construction sites.

  • Filtration is a method used for separating an insoluble solid from liquid using a filter paper.

  • Handpicking is a method used to separate a mixture using hands.

  • Distillation is a process used to separate components of a homogenous mixture. It involves heat and a sophisticated apparatus and does not come under 'simple physical methods.' 


So, sieving, handpicking and filtration are simple physical methods used to separate a heterogeneous mixture.
