Current Question (ID: 21194)

Question:

$\text{Which of the following cannot act as an oxidising agent?}$ $1. \text{MnO}_4^{-}$ $2. \text{SO}_4^{2-}$ $3. \text{N}_3^{-}$ $4. \text{BrO}_3^{-}$

Options:

1. $\text{MnO}_4^{-}$
2. $\text{SO}_4^{2-}$
3. $\text{N}_3^{-}$
4. $\text{BrO}_3^{-}$

Solution:

$\text{N}_3^{-} \Rightarrow \text{Because, it cannot further reduce itself to oxidise other.}$ $\text{N}_3^{-} \Rightarrow -3 \Rightarrow \text{lowest oxidation state}$ $\text{Others} \Rightarrow \text{Mn}^{+7}, \text{S}^{6+}, \text{Br}^{+5} \Rightarrow \text{can be self reduced and oxidise others.}$
