Question

name: q1 chemistry: u1l4 mixture types part 2: summarize the separation techniques teacher: date: uncommon schools change history type of separation when to use it write a summary distillation filtration evaporation *decanting / layer separation chromatography be uncommon. change history. page 3

Explanation:

• Distillation: Use when separating components of a liquid - liquid mixture with different boiling points. It involves heating the mixture to vaporize the more volatile component, then condensing it back to liquid.
• Filtration: Employed for separating an insoluble solid from a liquid. The mixture is poured through a filter paper, and the liquid passes through while the solid is retained.
• Evaporation: Used to separate a soluble solid from a liquid. The liquid is heated until it evaporates, leaving the solid behind.
• Decanting/Layer Separation: Applicable when separating immiscible liquids with different densities or a solid - liquid mixture where the solid has settled at the bottom. The top - layer liquid is carefully poured off.
• Chromatography: Utilized for separating mixtures of substances based on their different affinities for a stationary phase and a mobile phase. Components move at different rates through the stationary phase, leading to separation.

Answer:

Type of Separation	When to Use It	Write a Summary
Filtration	Separate insoluble solid from liquid	Pour mixture through filter paper, retain solid
Evaporation	Separate soluble solid from liquid	Heat liquid until it evaporates, leaving solid
Decanting/Layer Separation	Separate immiscible liquids or solid - liquid with settled solid	Pour off top - layer liquid carefully
Chromatography	Separate mixtures based on different affinities for phases	Components move at different rates through stationary phase
