| I. \[C{{u}_{2}}{{(OH)}_{2}}S{{O}_{4}}\] |
| II. \[C{{u}_{2}}{{(OH)}_{2}}C{{O}_{3}}\] |
| III. \[CuS{{O}_{4}}\] |
| IV. \[CuC{{O}_{3}}\] |
A) I and III
B) II and IV
C) I and IV
D) I and II
Correct Answer: D
Solution :
\[2Cu+{{H}_{2}}O+S{{O}_{3}}+{{O}_{2}}\to \] \[C{{u}_{2}}\,\,{{(OH)}_{2}}S{{O}_{4}}\] \[2C{{u}_{2}}+{{H}_{2}}O+C{{O}_{2}}+{{O}_{2}}\xrightarrow{{}}C{{u}_{2}}\,\,{{(OH)}_{2}}\,\,C{{O}_{3}}\]
