1看离子反应是否符合客观事实,不能主观臆造化学反应例如Fe与盐酸反应的离子方程式:2Fe+6H+=2Fe3+ +3H2↑,Fe与盐酸等弱氧化剂反应只能生成Fe2+,因此这样书写就不符合客观事实.
1 See if the ion reaction meets the objective facts, and cannot subjectively fabricate chemical reactions such as the ion equation of Fe and hydrochloric acid reaction: 2Fe+6H+=2Fe3++3H2↑. Fe2+ reacts with weak oxidants such as hydrochloric acid to generate Fe2+, so writing is not in accordance with this. Objective fact.
