A) \[C{{r}_{2}}O_{7}^{2-}\] ions are green.
B) \[C{{u}^{2+}}\] ions are green.
C) Both \[C{{r}_{2}}O_{7}^{2-}\] and \[C{{u}^{2+}}\] ions are green.
D) \[C{{u}^{2+}}\] ions are blue and \[C{{r}_{2}}O_{7}^{2-}\]ions are yellow.
Correct Answer: D
Solution :
[d] Green colour of \[CuC{{r}_{2}}{{O}_{7}}\] is due to blue colour of \[C{{u}^{2+}}\] ions and yellow colour of \[C{{r}_{2}}{{O}_{7}}^{2-}\]ions.You need to login to perform this action.
