Chemistry GK is an important branch of General Science. As you know we see various changes around us dues to chemical reactions. Through the study of chemistry GK, we learn how matter is formed, and the properties of the substance. In our daily, we use many things which are made by chemical reactions. Under the General Science section, chemistry, Biology, and Physics GK Questions are asked in competitive exams.
Here, I am sharing Chemistry GK Questions and Answers under the General Science section for those learners who are preparing for any competitive exams like SSC, RRB, RAS and other government exams. These types of Chemistry GK Questions are generally asked in competitive exams. If you want to crack the General Science section in competitive exams, you should keep a command of Chemistry GK Questions.
