# What is the oxidation state of chlorine in the salt, Ca(OCl)_2?

May 1, 2017

In calcium hypochlorite, we have $\stackrel{+ I}{\text{Cl}}$.

#### Explanation:

We assess $\text{^(-)"OCl}$, the hypochlorite ion, in ${\text{Ca(OCl)}}_{2}$, $\text{calcium hypochlorite}$. Of course this assignment is a formalism.

What are the oxidation numbers of $\text{Cl}$ in ${\text{ClO}}_{3}^{-}$, and ${\text{ClO}}_{4}^{-}$, $\text{chlorate}$, and $\text{perchlorate}$ ions respectively?
