已知氯化碘(ICl)的性质类似于卤素,有很强的化学活性。ICl跟Zn、H

已知氯化碘(ICl)的性质类似于卤素,有很强的化学活性。ICl跟Zn、H2O分别发生如下反应:2ICl+2Zn====ZnCl2+ZnI2,ICl+H2O====HCl+HIO,下列叙述正确的是(    )

A.在Zn跟ICl的反应中,ZnI2既是氧化产物又是还原产物

B.在Zn跟ICl的反应中,ZnCl2既不是氧化产物又不是还原产物

C.在H2O跟ICl的反应中,ICl既是氧化剂又是还原剂

D.在H2O跟ICl的反应中,ICl既不是氧化剂又不是还原剂

答案

AD


解析:

ICl中I呈+1价、Cl呈-1价,故2+2====是氧化还原反应,ZnCl2是氧化产物,ZnI2既是氧化产物也是还原产物。+H2O====H+HO不是氧化还原反应。
