A) iodide is a bulky ion
B) \[C{{u}^{2+}}\]oxidizes iodide to iodine
C) \[C{{u}^{2+}}(aq)\]has much more negative hydration enthalpy
D) \[C{{u}^{2+}}\]ion has smaller size
Correct Answer: B
Solution :
All Cu (II) halides are known except the iodide because\[C{{u}^{2+}}\]oxidizes iodide to iodine. \[2CuS{{O}_{4}}+4KI\xrightarrow[{}]{{}}2CuI\downarrow +{{I}_{2}}\] \[{{I}_{2}}\]is produced by oxidation of I which reduces\[C{{u}^{2+}}\]to\[CuI\].You need to login to perform this action.
