A technique for separating mixtures based on the different rates at which components move across a medium.

A separation technique that uses boiling and condensation to separate liquids based on different boiling points.

A process that separates a mixture of liquids into its components using a fractionating column to enhance separation.

A process where a solid forms in a pure state from a solution as it cools or evaporates.

A method of separation where a solid turns directly into gas without passing through a liquid state.

A laboratory apparatus used for separating immiscible liquids based on their ability to not mix.

A technique that separates solids from liquids based on particle size or solubility differences in a solvent.

In chromatography, a starting line needs to be drawn in pencil and not ink to prevent interference in results.

Methods used to separate components in mixtures based on physical properties.

A mixture where two liquids can be miscible (mix completely) or immiscible (not mix).

The process of turning liquid into vapor, leaving solids behind.

The ratio of the distance traveled by a substance to the distance traveled by the solvent in chromatography.

Substances used in chromatography to visualize colorless compounds.

The temperature at which a solid melts or a liquid boils, key for identifying substances.

A drying agent that cannot dry ammonia due to forming ammine complexes.

Techniques used to gather gases based on their solubility and density variations.

Hydrogen is collected using an upward displacement of air due to being less dense than air.

Oxygen is collected using downward displacement of water as it is slightly denser than air.

Carbon dioxide is collected using downward displacement of water, as it is denser than air.

Different components of a mixture travel at different speeds due to varying solubility in the solvent.

Locating agents reveal colorless spots on chromatograms by creating colored reactions.

The standard unit for measuring volume in the metric system.

A smaller unit of volume measurement, often used for liquids.

An instrument used to measure variable volumes of liquid accurately.

Device used to measure the volume of gases.

Method for collecting gases that are insoluble in water.

Method for collecting gases that are less dense than air.

Substances used to remove moisture from gases.

A strong drying agent used to remove moisture from gases.

A process to separate a liquid from a solution by heating and cooling, collecting the vapor.

A method for separating immiscible liquids, taking advantage of their differing densities.

Method to obtain sugar crystals from a sugar solution by cooling and evaporation.

Higher temperatures increase the solubility of sugar in water.

Faster cooling rates produce smaller crystals, while slower cooling creates larger ones.

Heating sugar or copper (II) sulfate solutions to dryness caramelizes or forms solid.

The thermometer bulb is placed at the condenser outlet to measure vapor temperature.

Cooling water enters the condenser at the bottom (B) to ensure effective cooling.

Antidumping granules prevent bumping during boiling in distillation.

A technique showing purity through distinct spots: one for pure, multiple for impure.
