在现行教材中从初三的溶解平衡,到高一的化学平衡,以至高二的电离平衡、水解平衡及简单涉及的络合平衡,已形成了一个初步的平衡理论体系。有意识地在教学中将它们加以归纳,有助于使平衡理论知识系统化。同时,应用平衡理论渗透一些重要化学概念,指导元素化合物知识的教学,也有助于加强化学的说理性,减少单纯叙述的色彩。笔者认为,平衡理论在中学化学教学中的
In the current teaching materials, a preliminary balance theory system has been formed from the dissolution balance of the third grade, to the chemical balance of the first grade, to the balance of ionization of the second grade, the balance of hydrolysis, and the complex balance involved in simple hydrolysis. Consciously summarizing them in teaching helps to systematize balanced theoretical knowledge. At the same time, applying the balance theory to infiltrate some important chemical concepts and guiding the teaching of elemental compound knowledge also helps to strengthen the rationality of chemistry and reduce the color of simple narratives. The author believes that the theory of balance in chemistry teaching in middle school
