The chemical experiment is a compulsory examination content of the college entrance examination, and it has a relatively high score in the high exam volume. Analysis of high test questions in recent years found that the chemical experiment part mainly examines the use of instruments, the access and storage of drugs, the use of instruments, the separation and purification of substances, the preparation of gases, the purpose and the principle of experiments. Test Site I. Use of Common Instruments This test site is intended to examine the use of instruments commonly used in middle school chemistry, how to use them, and whether the combinations in each operation are correct.
