Lab Equipment

Question 1

Beaker

Answer 1

Holds solids or liquids that will not release gases when reacted or unlikely to splatter if stirred or heated

Question 2

Erlenmeyer Flask

Answer 2

Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter when stirred or heated

Question 3

Florence Flask

Answer 3

Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure

Question 4

Graduated cylinder

Answer 4

A graduated cylinder is used to measure volumes of liquids

Question 5

Gas Collecting Bottle

Answer 5

We use large gas collecting bottles when large volumes of gasses are produced, and must be collected by the displacement of water

Question 6

Test Tube Holder

Answer 6

A test tube holder is useful for holding a test tube which is too hot to handle

Question 7

Test Tube Brushes

Answer 7

Test tube brushes are used to clean the test tubes and graduated cylinders. Forcing a large brush into a small test tube will often break the tube

Question 8

Test Tube Racks

Answer 8

Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes

Question 9

Rubber Stoppers

Answer 9

Rubber stoppers are used to close containers to avoid spillage or contamination. Containers should never be heated when there is a stopper in place.

Question 10

Spot Plates

Answer 10

Spot plates are used when we want to perform many small scale reactions at one time. we will use these many times during the year

Question 11

Watch Glass

Answer 11

A watch glass is used to hold a small amount of solid, such as the product of a reaction

Question 12

Glass Stir Rod

Answer 12

A glass stir rod is used to manually stir solutions. It can also be used to transfer a single drop of solution

Question 13

Medicine Dropper

Answer 13

A medicine dropper is used to transfer a small volume of liquid

Question 14

Question 18

Spatulas

Answer 18

Spatulas are used to dispense solid chemicals from their containers. Chemicals should never be transferred with your bare hands.

Question 19

Beaker Tongs

Answer 19

Beaker tongs are used to move beakers containing hot liquids.

Question 20

Bunsen Burner

Answer 20

Question 22

Clay Triangle

Answer 22

Used to support porcelain crucibles when being heated over a Bunsen burner

Question 23

Crucible Tongs

Answer 23

Used to pick up hot objects and hot crucibles. NOT BEAKERS

Question 24

Glass Plates

Answer 24

Provide a surface for semi-micro scale experiments, such as drop reactions and testing of acids and bases

Question 25

Ringstands and components

Answer 25

A save and convenient way to perform reactions that require heating using a Bunsen burner.

Question 26

Iron Rings

Answer 26

Connected to ringstand to provide stable and elevated platform for reactions
