General Chemistry is designed to give a general but fundamental understanding of chemical principles to undergraduate students majoring in science and engineering. General Chemistry also aims to attract more undergraduate students to carry out chemical research at their seniors.The topics of General Chemistry include: atoms and elements, molecular and electronic structures, states of matter, bonding, chemical equilibriums, kinetics and thermodynamics, stoichiometry, aqueous solution chemistry, acids and bases, oxidation and reduction, and so on.As chemistry is an experimental science, a very special point for teaching General Chemistry for undergraduate students is to emphasize the experimental aspect of a chemical reaction and create every possible condition for students to practice the reactions in a safe chemical laboratory. Also, the students should be educated that chemistry is practically useful and it helps us to understand the world around us at the molecular level and to create every materials and events in our daily life.
