Question: What is the possible oxidation state of chlorine present in bleaching powder-
Options:
A) +1
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.
