A chemical experiment is a procedure designed to test a hypothesis as part of the scientific method. The two key variables in any experiment are the independent and dependent variables. The independent variable is controlled or changed to test its effects on the dependent variable. A chemical experiment illustration shows how a chemistry experiment looks when performed in a chemistry laboratory with the right glassware and equipment like a beaker, beaker tongs, bunsen burner, buret, clay triangle, the crucible, crucible tongs, test tubes, and others. Tools like EdrawMax and EdrawMax Online provide all the chemistry laboratory symbols that can be helped in creating chemistry diagrams or presentations.
