A) +1
B) - 1
C) Both - 1 and +1
D) zero
Correct Answer: C
Solution :
| [c] Idea this problem includes conceptual mixing of formula of bleaching powder and oxidation state calculation. |
| ?Write the chemical formula |
| ? Then, calculate oxidation state of Cl. |
| Formula of bleaching powder is |
| \[CaOC{{l}_{2}}=\underset{\begin{smallmatrix} \uparrow \\ hypochloride \end{smallmatrix}}{\mathop{Ca(OCl)Cl}}\,\] |
| \[OC{{l}^{-}}\to \] oxidation state of \[Cl=-2+x=-1\]\[x=+1\] |
| \[C{{l}^{-}}\to \] oxidation state of \[Cl=-1\] |
| So, [c] is the correct choice. |
| TEST Edge Oxidation states of some more compound are also asked frequently. |
