Shaking bromine water with chloroform is a common test to detect the presence of unsaturation in a compound. If an alkene is present, it will react with bromine to decolorize the bromine water, forming a colorless solution due to the addition of bromine across the double bond. This test is known as the bromine test for unsaturation.

Test tubes are used in laboratories to store, to mix or to change the heat of chemicals.
To put chemicals Into it to create a formula. It is easier in a test tube because it fits nicely into your hand
Test Tube racks are used in Chemistry to store and hold test tubes. Because test tubes have a rounded bottom they cannot stand on thereselves, therefore the rack holds and stores them.
Often, there are better ways to test a substance than an odor test. If necessary, carefully and gradually waft the vapor toward your nose. Don't stick your nose in or over the testtube.
A micrometer or caliper can be used to measure the diameter of a test tube accurately. These tools provide precise measurements by directly reading the diameter of the test tube in millimeters.
A thermoscope is typically made of a glass tube filled with a liquid such as alcohol or mercury. It has a bulb at one end and a narrow tube extending from the bulb. The liquid expands and rises in the tube when the temperature increases.
A laboratory stand or support stand is commonly used to hold equipment like beakers, flasks, or test tubes at a desired height or position during experiments. The stand typically consists of a base, a vertical rod, and clamps or rings to secure the apparatus in place.
