The redox reaction among the following is :
Solution
N<sub>2</sub> + O<sub>2</sub> $\to$ 2NO
<br><br>during the reaction, oxidation of nitrogen take place
from 0 to 2 and reduction of oxygen take place
from 0 to –2. It means this reaction is redox
reaction.
<br><br>3O<sub>2</sub> $\to$ 2O<sub>3</sub> (Non - redox reaction)
<br><br>2NaOH + H<sub>2</sub>SO<sub>4</sub> $\to$ Na<sub>2</sub>SO<sub>4</sub> + 2H<sub>2</sub>O (neutralization reaction)
<br><br>[Co(H<sub>2</sub>O)<sub>6</sub>]Cl<sub>3</sub> + 3AgNO<sub>3</sub>
$\to$ 3AgCl $\downarrow$ + [Co(H<sub>2</sub>O)<sub>6</sub>](NO<sub>3</sub>)<sub>3</sub>
<br><br>Reaction of [CO(H<sub>2</sub>O)<sub>6</sub>]Cl<sub>3</sub> with AgNO<sub>3</sub> is not
redox reaction. It is a precipitation reaction.
