Solution

A chemistry laboratory generally has the following facilities.

Workbenches at which two or three people can work are present.
Each bench has stand for holding common chemicals in bottles, a gas burner, and a sink.
Special chemicals and concentrated acids are stored on a separate shelf.
Balances for weighing chemicals are kept in a separate room or area.
A fume cupboard is used to keep substances that give off fumes.
Apparatus-
Different types of equipment are used in a laboratory. The items used for storing and handling chemicals are called apparatuses. Some of the kinds are:

apparatuses for storing, heating, or cooling chemicals
apparatuses for measuring
apparatuses for stirring, transferring or covering chemicals apparatuses for supporting or holding.

Most of the apparatuses in which chemicals are taken are made of glass.
The reasons are as follows.
Glass is transparent, so we can see what is happening inside.
Glass can be washed thoroughly. Glass does not react with most chemicals.
Glass withstands both high and low temperatures.
Glass can be formed easily into whatever size and shape is required.
Some apparatus used in chemistry laboratory are:
Name Description Use
test tube a glass tube open at one end and rounded at the other to study or heat small quantities of reagents
beaker made of glass, is of different sizes and has a rim and a spout to mix, stir and heat reagents
round-bottom flask (Florence flask) has a narrow neck and a round body to mix or heat reacting liquids,can be swirled without spilling the contents
conical flask has a narrow neck and triangular body to mix large quantities of reagents without spilling the contents.
china dish made of porcelain and is of different sizes to evaporate liquids
glass trough a round, oval or square glass container to hold large quantity of liquid
reagent bottle a bottle made of clear or coloured glass; it can be closed with a stopper to store reagents.
