Chemistry Laboratory Apparatus Quiz

The time interval between two events.

The standard unit of time measurement in the International System of Units (SI).

An instrument used to measure the interval of time.

The degree of hotness or coldness of a substance. It is measured using a thermometer.

The standard unit of temperature measurement in the International System of Units (SI).

A scale for measuring temperature where the freezing point of water is 0°C and the boiling point is 100°C.

The amount of matter in an object. Measured using a balance.

The standard unit of mass measurement in the International System of Units (SI).

The process of separating a mixture of a soluble solid and an insoluble solid by dissolving the soluble solid in a suitable solvent.

A technique used to separate a sublimable solid from a non-sublimable solid by heating the mixture. The sublimable solid changes directly from solid to gas, leaving the non-sublimable solid behind.

A method used to separate an insoluble solid from a liquid by passing the mixture through a filter paper. The solid residue remains on the filter paper, while the liquid filtrate passes through.

A technique used to separate a dissolved solid from its solvent by heating the solution. The solvent evaporates, leaving the solid behind.

The process of separating a mixture by heating it, where the component with the lower boiling point vaporizes first and can be collected separately. This method is mainly used for mixtures of liquids.

A technique used to separate a mixture of two liquids with different boiling points by heating the mixture and collecting the vapor of the component with the lower boiling point.

A method used to separate a mixture of two solids with different densities by using a separating funnel. The denser solid settles at the bottom, while the lighter solid stays at the top.

A technique used to separate a mixture of two solids with different magnetic properties by using a magnet. The magnetic solid is attracted to the magnet, while the non-magnetic solid remains unaffected.

The process of separating a mixture into its individual components based on their different solubilities.

Substances that dissolve more easily travel faster in the chromatography process.

A chromatography method using paper strips to separate and identify substances.

A single substance will produce only one spot on a developed chromatogram.

A mixture will result in multiple spots on a developed chromatogram, with each spot representing a component of the mixture.

A substance with a higher boiling point will liquefy first when a mixture of gases is cooled.

The process of separating solid crystals from a solution by filtering the solution through a filter paper to collect the crystals.

The ability of a substance to change from a liquid to a gas at a specific temperature. A more volatile substance will turn into a gas more easily.

A tall, vertical column filled with glass beads or other packing material that helps separate liquids with different boiling points. The column provides a surface for repeated condensation and vaporization, increasing the purity of the collected liquids.

Liquids that do not mix together, forming separate layers when combined. An example is oil and water.

A solid that dissolves in a solvent, typically water.

A solid that does not dissolve in a solvent, such as water.

A colorless chemical used to reveal the presence of amino acids on a chromatogram by reacting with them to form colored compounds.

The ratio of the distance traveled by the center of a spot to the distance traveled by the solvent front. It helps identify components in a mixture.

The point where a sample is initially applied to the chromatography paper.

The highest point reached by the solvent on the chromatography paper. It helps determine the Rf value.

The distance traveled by a component from the start line to its final position on the chromatogram.

The distance traveled by the solvent front from the start line to its highest point on the chromatogram.

A technique used to analyze a mixture's components, particularly suitable for identifying colorless substances, like amino acids.

A method used to separate mixtures based on the different solubilities of the components in a specific solvent. The soluble component dissolves in the solvent, while the insoluble component remains as a solid residue.

A technique used to obtain solid crystals from a saturated solution. The solution is heated to evaporate some of the solvent, making it more concentrated. As the solution cools, the solubility of the solute decreases, causing the excess solute to crystallize out.
