Among the properties (A) reducing (B) oxidizing (C) completing, the set of properties shown by\[C{{N}^{-}}\]ion towards metal species is
A)A, B
B) B, C
C) C, A
D) A, B, C
Correct Answer:
C
Solution :
is a better complexing agent (C) as well as a reducing agent (A) Thus properties (A) and (C) are shown, Property Property (A)\[CuC{{l}_{2}}+5KCN\xrightarrow{\,}\] (reducesto)
