Current Question (ID: 8605)

Question:

$\text{Which is the correct set that can only act as an oxidant?}$

Options:

1. $\text{NO}_3^-, \text{SO}_3, \text{Na}$
2. $\text{Fe}^{+3}, \text{NO}_3^-, \text{SO}_3$
3. $\text{I}^-, \text{Na}$
4. $\text{I}^-, \text{NO}_3^-$

Solution:

$\text{Hint: Element in its highest oxidation state can act as only OXIDANT}$ $\text{For } \text{Fe}^{3+}, \text{NO}_3^-, \text{SO}_3:$ $\text{Fe}^{3+} \text{ has oxidation state } +3$ $\text{NO}_3^- \text{ has N with oxidation state } +5$ $\text{SO}_3 \text{ has S with oxidation state } +6$ $\text{The central atom has a maximum oxidation state, so it will only act as an oxidizing agent.}$
