Chemistry and its importance
Importance of Chemistry
Science and especially chemistry require a lot of experimentation and various types of things are required for carrying out these experiments. The substances that are required to carry out experiments are known as apparatus. Some common apparatus that are required in a chemistry laboratory are discussed below.
Test tube: It is a glass tube with one end open and the other closed. The test tubes are of different types and made of different types of glass. The test tube which can be heated directly on flame is called hard glass test tube or boiling test tube. Such test tubes are made of pyrex glass.
Test tube stand: It is a plastic or wooden stand for keeping test tubes. It has holes as well as bars to keep the test tubes upright and in inverted position respectively.
Test tube holder: It is an iron tong with plastic or wooden handle. It is used to hold a test tube when the substance is being heated or strong chemicals such as acids or alkalis are being poured into the test tube.
Beaker: It is an open glass container with a lip for pouring liquids. It is of various sizes and is used to store and mix chemicals.
Round-bottom flask: It is a glass container with a spherical bulb and a narrow cylindrical neck. It is generally used for heating liquids.
Flat-bottom flask: It is a glass container having a spherical bulb with a flattened base and a narrow cylindrical neck. It is used for storing and mixing liquid chemicals and should not be used for heat…
