高中化学错题精集1
高中化学错题集例题1、在某100ml的混合液中，硝酸和硫酸的物质量浓度分别是0.4mol/L,0.1mol/L,向该混合液中加入 1.92g铜粉,加热,待充分反应后,所得溶液中铜离子物质量浓度是(mol/L):A 0.15B 0.225C 0.35D 0.45容易错选答案为A错误原因：根据反应：3Cu + 8HNO3 = 3Cu（NO3）2 + 2NO + 4H2O，题目中给出的硝酸的物质的量为0.04mol，因此，参与反应的铜的物质的量为0.015mol，因此答案为A。
解题时忽略溶液中仍然存在H+，在该条件下，生成的Cu（NO3）2中的硝酸根离子要和铜继续反应。
正确解答思路为：根据3Cu + 8H+ +2NO3- ==3Cu2+ +2NO +4H2O3 8 2 30.03 0.06 0.04 XX=3*0.6/8=0.0225mol因此，铜离子浓度为0.225MOL/L例题2、为了测定某铜银合金成分，将30g合金完全溶于80ml13.5mol/L的浓硝酸中，待反应完全后，收集到6.72L气体(标况),并测得溶液中H离子浓度是1mol/L.假设反应后溶液体积仍为80ml,求合金中银的质量分数.错解：假设银的质量分数为X，则：Ag + 2HNO3 = AgNO3 + NO2 + H2O30X /108 60X/108 30X/108Cu + 4HNO3 = Cu（NO3）2 +2NO2 +2H2O30（1-X）/64 120（1-X）/64 60（1-X）/64根据气体体积关系有： 30X/108 + 60（1-X）/64=0.3，解得X或根据HNO3量的关系有：60X/108 +120（1-X）/64=0.08*（13.5-1），解得X错误原因：没有考虑到硝酸浓度的变化。
正确解答为：假设铜、银的物质的量依次为X、Y，则有64X+108Y=30（固体质量关系）2X+Y+0.3=0.08*（13.5-1）（硝酸中N的守恒），从而得到X=0.1mol，即银的质量为23.6g 质量分数为78.7%例题3、标准状况下，往100mL 0.2mol/L的FeBr2溶液中通入一定体积的Cl2，充分反应后，溶液中有50%的Br-被氧化。
