The process of separating two immiscible liquids uses:
A. Separating funnel
B. Centrifuge
C. Fractionating column
D. Condenser
Answer: Option A
Solution (By JKSSB Mock Tests)
A separating funnel allows immiscible liquids to form layers; the denser liquid is drained from the bottom. Fractionating column is for miscible liquids with close boiling points, condenser for distillation, centrifuge for separating fine solids or liquids of different densities by spinning.
Explanation:
Liquids have a definite volume but take the shape of their container. Solids have the least intermolecular space and highest density. Gases have maximum intermolecular space and are highly compressible. This relates directly to the kinetic theory of matter, which describes particle arrangement and movement in different states.
Explanation:
Graham's law of effusion/diffusion applies to gases. It states that rate is inversely proportional to square root of molar mass. It is used to separate isotopes.
Explanation:
The zeolite (permutit) process is used to remove water hardness. Zeolite (hydrated sodium aluminum silicate) exchanges its Na⁺ ions for the Ca²⁺ and Mg²⁺ ions in hard water, thus softening it. It does not remove bacteria, dissolved gases, or suspended solids.
