Question

Substances W, X, Y, and Z are obtained from different types of mixtures by using appropriate separating processes as shown in the given flowchart: Separating processes used to obtain W, X, Y, and Z respectively are:

• A. Winnowing, filtration, sedimentation and evaporation
• B. Handpicking, sedimentation, winnowing, and evaporation
• C. Sieving, evaporation, filtration and separating funnel
• D. Sedimentation, winnowing, filtration and separating funnel

Answer 1

The correct option is C Sieving, evaporation, filtration and separating funnel

There are different types of separating techniques for a different type of mixtures.
$\bullet$ Handpicking, sieving, winnowing, and threshing are used to separate solid-solid mixtures.
$\bullet$ Evaporation, and condensation are used to separate soluble solid-liquid mixtures.
$\bullet$ Sedimentation and decantation, filtration, and churning are used to separate insoluble solid-liquid mixtures.
$\bullet$ Sedimentation and decantation, and separating funnel are used to separate immiscible liquid-liquid mixtures. Therefore option D is the correct answer.
