Abstract Senior high school textbook Principle of Chemical Reaction added four contents:chemical equilibrium constant, ionization constant, hydrolysis constant of salt, solubility product constant.Chemical constants were comprehensive figures after long period of experiments and human deduction, which contained chemical knowledge, methods of scientific experiment and the wealth of human spirit. In high school chemistry teaching, constants could enhance students' view of the nature of science, the concept of scientific methods and human spirit, which would help to improve students' scientific literacy.
