离子方程式的书写及离子方程式的正误断判是高考的重要考点,酸式盐与碱反应的离子方程式书写是中学化学的重点、难点内容之一。由于反应物的量不同,离子方程式不同,许多学生在书写酸式盐与碱反应的离子方程式时,常感到无从下手,结合笔者在教学中的所得,现介绍设1法,以供参考。 The writing of the ion equation and the correctness and misjudgment of the ion equation are important test points for the college entrance examination. The ion equation equation of the reaction between the acid salt and the alkali is one of the key and difficult contents of middle school chemistry. Due to the different amounts of reactants and different ion equations, many students often feel that they can’t start with the ion equations that describe the reaction between acid salts and alkalis. In combination with the author’s income from teaching, the method of setting 1 is presented for reference.
