W1: Lab Apparatus Uses Flashcards
Identify the proper usage of each apparatus
_______ hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
Beakers
_______ are used to move beakers containing hot liquids
Beaker tongs
_______ hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.
Erlenmeyer flasks
_______ are Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.
Florence Flask
_______ is used to measure volumes of liquids.
graduated cylinder
________ is useful for holding a test tube which is too hot to handle.
test tube holder
_______ are used to clean test tubes and graduated cylinders. Forcing a large brush into a small test tube will often break the tube.
Test tube brushes
_______ are for holding and organizing test tubes on the laboratory counter. After washing flip test tube over on wooden peg to dry.
Test tube racks
_______ are used to close containers to avoid spillage or contamination. Containers should never be heated when there is a stopper in place.
Rubber stoppers
________ are used when we want to perform many small scale reactions at one time.
