Lab Equipment

Question 1

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

Answer 1

Beaker

Question 2

hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.

Answer 2

Erlenmeyer Flask

Question 3

the spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents.

Answer 3

Test Tubes

Question 4

is used to measure volumes of liquids.

Answer 4

Graduated Cylinder

Question 5

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

Answer 10

Spot Plates

Question 11

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

Answer 11

Answer 15

Litmus Paper

Question 16

used to aid in the transfer of liquid from one vessel to another.

Answer 16

Funnel

Question 17

has a spout that delivers a wash solution a specific area. Distilled water is the only liquid that should be used in this.

Answer 17

Wash Bottle

Question 18

used to weigh solids that will be transferred to another vessel.

Answer 18

Weighing Boat

are used to move beakers containing hot liquids.

Answer 21

Beaker Tongs

Question 22

are used for heating certain solids, particularly metals, to very high temperatures.

Answer 22

Crucible

Question 23

for handling hot crucibles; also used to pick other hot objects. NOT to be used for picking up beakers!

Answer 23

Crucible Tongs

Question 24

are a safe and convenient way to perform reactions that require heating using a Bunsen Burner.

Answer 24

Ringstands and their Components

Question 25

connect to a ringstand and provide a stable, elevated platform for the reaction.

Answer 25

Ringstands and their Components Iron Rings

Question 26

are used to secure test tubes, distillation columns, and burets to the ringstand.

Answer 26

Ringstands and their Components Utility Clamps

Question 27
