Current Question (ID: 21191)

Question:

$\text{What is the oxidation number of Cl in CaOCl}_2 \text{ (bleaching powder)?}$

Options:

1. $\text{Zero, because it contains Cl}_2$
2. $-1, \text{ because it contains Cl}^-$
3. $+1, \text{ because it contains ClO}^-$
4. $+1 \text{ and } -1 \text{ because it contains ClO}^- \text{ and Cl}^-$

Solution:

$\text{Hint: Cl show two different oxidation states}$ $\text{The CaOCl}_2 \text{ is a bleaching powder. It is written as Ca(OCl)Cl.}$ $\text{The oxidation state of Cl in OCl}^- \text{ is } +1 \text{ and the Cl directly attached with Ca, oxidation state is } -1.$
