氧化还原反应是最为重要的化学反应类型,涉及知识的内容广泛、概念众多,在计算应用时稍不注意就容易出错.对学生来讲,要谨防以下易错情形,以提高学习成绩.一、氧化剂与还原剂的量之比例1在反应3NO2+H2O=2HNO3+NO中,氧化剂与还原剂的分子数之比为()(A)2∶1(B)1∶2(C)3∶1(D)1∶3错误分析:选(A)项.在答题时将氧化剂与还原剂的量弄 Redox reaction is the most important type of chemical reaction, involving a wide range of knowledge, many concepts, in the calculation of the application is not easy to make mistakes.For students, beware of the following error-prone situations in order to improve academic performance.A, The ratio of the amount of oxidant to the amount of reducing agent in the reaction 3NO2 + H2O = 2HNO3 + NO, the ratio of the number of molecules of oxidant and reducing agent is (A) 2: 1 (D) 1: 3 Error Analysis: Select (A). In the answer to the amount of oxidant and reductant
