Redox Reactions

%5E%7B2%2B%7D

is a strong oxidising agent. Iodide (I

%5E%7B-%7D

) is easily oxidised to I

_2

. Therefore, when we attempt to make CuI

_2

, the following redox reaction occurs:

2%5Ctext%7BCu%7D%5E%7B2%2B%7D%20%2B%204%5Ctext%7BI%7D%5E%7B-%7D%20%5Crightarrow%202%5Ctext%7BCuI%7D%20%2B%20%5Ctext%7BI%7D_2

Thus, Cu

%5E%7B2%2B%7D

is reduced to Cu

%5E%2B

, and I

%5E%7B-%7D

is oxidised to I

_2

. Hence, CuI

_2

is unstable and not known.
