Flashcards

Decanting

A separation technique that uses density differences to separate a less dense liquid from a denser solid or liquid.

Suspension

A mixture where one substance is dispersed evenly throughout another, but does not dissolve. The particles of the dispersed substance are visible.

Solvent

A liquid that dissolves another substance to form a solution.

Immiscible liquids

Liquids that do not mix together. They form separate layers.

Study Notes

Decanting Principle

Decanting separates substances based on density differences.
The denser component sinks to the bottom.
The less dense component is poured off.
Common application: separating liquid from solid in a suspension.

Decanting Process

Liquids with different densities are poured off one at a time into a separate container.
The less dense liquid is poured into a separate container to avoid spilling the denser liquid.
A separating funnel is used for immiscible liquids (liquids that do not mix).
The separating funnel has a stopcock that allows controlled pouring.
