离子方程式是中学化学的重点和难点,更是高考中的必考点,同学们在考试过程中,得分率较低,下面根据《山东科学技术出版社》实验教科书的内容,与同学们探讨一下:教材方法引导内容中,是这样给出的:1.写出化学方程式盐酸与氢氧化钠在溶液中发生反应的化学方程式:HCl+NaOH=NaCl+H2O2.改写化学方程式将化学方程式中易溶解于水且易电离的物质改用离子符号(即该物质电离产物的符号)表示,而难溶于水的物
Ion equation is the focus of high school chemistry and difficulties, but also the college entrance examination will be the test center, the students in the examination process, the score is low, following the “Shandong Science and Technology Press” experimental textbook content, and students to explore: The textbook guide is given as follows: 1. Write the chemical equation for the reaction of hydrochloric acid with sodium hydroxide in solution: HCl + NaOH = NaCl + H2O2. Rewrite Chemical Equation The chemical equation is easily dissolved in Water and easily ionized substances to ion symbols (ie, the material ionization product symbols), while the water-insoluble substances
