化学像其它学科一样在教学过程中会遇到一些容易混淆的概念 ,之所以容易混淆 ,是因为它们“形相近、意不同”。在教学过程中必须引起足够的重视才有利于提高教学效果。现就初中化学中容易混浠的几组概念辨析如下 :一、盐与食盐盐是“电离时生成金属离子和酸根离子的化合物”。?
Chemistry, like other disciplines, will encounter some confusing concepts in the teaching process. The reason why it is easy to confuse is because they are similar in shape and different in meaning. In the teaching process, we must pay enough attention to help improve teaching effectiveness. Now, several groups of concepts that are easy to mix in junior high school chemistry are identified as follows: First, salt and salt are “compounds that generate metal ions and acid ions when ionized”. ?
