A) \[C{{u}_{2}}{{(SCN)}_{2}}\]
B) \[C{{u}_{2}}O\]
C) \[C{{u}_{2}}{{I}_{2}}\]
D) \[C{{u}_{2}}C{{O}_{3}}\]
Correct Answer: A
Solution :
[a] \[C{{u}_{2}}{{(SCN)}_{2}}\] It is a white precipitate. It is used for the gravimetric estimation of Cu(II) by first reducing it with \[{{H}_{2}}S{{O}_{3}}\]and then complexing Cu(I) thus obtained with\[SC{{N}^{}}\].You need to login to perform this action.
