Chemistry quiz

Goggles

Goggles

used for protection against chemical splash hazards, use of concentrated corrosive material, and bulk chemical transfer.

wash bottle

used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks. To clean laboratory glassware and other equipment. They are filled with appropriate cleaning liquids, and poured over the tool that needs to be cleaned.

apron

Wear protective clothing that resists physical and chemical hazards when exposure may occur. Lab coats are appropriate for minor chemical splashes and solids contamination, while plastic or rubber aprons are best for protection from corrosive or irritating liquids.

balance

used to weigh small amounts of substances accurately up to the fourth place of decimal.

beaker

Beakers can be used to hold liquid or solid samples or as a container for reactions. They are also used to collect filtrates from filtering operations as well as liquids from titrations. It is used for stirring the liquid.

Erlenmeyer Flask

Erlenmeyer flasks are important tools for scientific laboratories. They are used for mixing and storing chemicals and solutions. These flasks come in various sizes, are made of glass, and can be autoclaved. However, they cannot be used for accurate measurements of solutions

Test tube

to handle chemicals, especially for qualitative experiments and assays.

Test tube rack

to hold upright multiple test tubes at the same time.

Test tube clamp

to hold test tubes securely during procedures like heating, mixing and transferring them

Graduated Cylinder

Graduated cylinders are used to measure the volume of liquids.

Thermometer

to measure the boiling point and freezing point during science experiments

Evaporating Dish

to contain samples of liquids that require evaporation.

Mortar & Pestle

to crush up solid chemicals into smaller pieces, or to grind solids into fine powder. This makes it easier to dissolve solids into solvents (when making solutions).

Watch glass

A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker.

Crucible & Lid

Usually made from porcelain or metal, crucibles enable chemical compounds to be heated to very high temperatures. They are sometimes used in conjunction with a loose fitting lid made of a similar material. The lid is purposely loose to allow gases to escape during heating

Wire Gauze

Wire gauze or wire mesh is a gauze woven of metal wire, or very fine, gauze-like wire netting. Wire gauze is placed on the support ring that is attached to the retort stand between a burner and glassware, or is placed on a tripod to support beakers, flasks, or other glassware to protect it during heating.

Crucible Tongs

used to lift a hot crucible from a furnace or for other items which cannot be handled with bare hands. Crucible tongs may also be used to prevent any inaccuracies regarding mass measurements as any moisture or oil will affect the readings and accuracy.

Ring Stand

In chemistry, a retort stand, also called a clamp stand, a ring stand, or a support stand, is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks.

Bunsen Burner

A Bunsen burner is a type of gas burner that is used in many chemistry procedures in a laboratory setting. It is used to heat substances, to combust substances, and to sterilize objects on high heat. Many different types of gases can be used in a burner such as methane, butane, propane, or a mixture of them.

Hot Plate

The primary function of a laboratory hot plate is to heat substances in containers such as beakers, flasks or test tubes. The heated substances are then utilized for various applications, such as chemical synthesis and sample preparation.

Funnel

filtering, filling, decanting or transferring liquids or powders from one vessel to another.

Rubber Stoppers

Rubber stoppers are commonly used in chemistry, biology, and other scientific fields for tasks such as sealing test tubes, flasks, and other containers during experiments or storage. They can also be used in industrial settings for sealing pipes and other equipment.

Spatula/Scoopula

Scoopula is a brand name of a spatula-like scoop utensil used primarily in experimental laboratories to transfer solids: to a weighing paper for weighing, to a cover slip to measure melting point, or a graduated cylinder, or to a watch glass from a flask or beaker through scraping.

Clay Triangle

used to support a crucible being heated by a Bunsen burner or other heat source.
