4.用如图所示的微型实验装置进行氯气性质探究。验时滴几滴浓盐酸。下列说法错误的是是滴有相应溶液的滤纸条,实A.②③处滤纸均先变红后褪色B.④处滤纸变蓝色,推测氧化性:Cl2>I2C.⑤处发生反应:Cl2+2Fe^2+2Cl^-+2Fe^3+、3SCN^-+Fe^3+Fe(SCN)3D.浓盐酸与KMnO4反应体现浓盐酸的还原性和酸性

14.①现有6.6g铜镁合金与一定量浓硝酸恰好完全反应,得到NO2、NO的混合气体(不考虑N2O4等其它气体)体积为4.48L(本题气体体积均为标准状况下):②这些气体与一定体积氧气混合后通入水中,所有气体完全被水吸收生成硝酸。若向①所得溶液中加入5mol/LNaOH溶液至金属离子恰好完全沉淀,消耗NaOH溶液的体积是60mL。下列说法不正确的是()A.①中参加反应的硝酸是0.5molB.②中消耗氧气的体积是1.68LC.铜镁合金中镁的质量为2.4gD.混合气体中NO2体积为3.36L
