B) - 1

C) Both - 1 and +1

D) zero

Show Answer

Answer:

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 $ CaOCl_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.
