JEE MAIN - Chemistry (2020 - 7th January Evening Slot - No. 8)
The redox reaction among the following is :
reaction of H2SO4 with NaOH.
formation of ozone form atmosphere oxygen in the presence of sunlight.
combination of dinitrogen with dioxygen at 2000 K
reaction of [Co(H2O)6]Cl3 With AgNO3
Explanation
N2 + O2 $$ \to $$ 2NO
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.
3O2 $$ \to $$ 2O3 (Non - redox reaction)
2NaOH + H2SO4 $$ \to $$ Na2SO4 + 2H2O (neutralization reaction)
[Co(H2O)6]Cl3 + 3AgNO3 $$ \to $$ 3AgCl $$ \downarrow $$ + [Co(H2O)6](NO3)3
Reaction of [CO(H2O)6]Cl3 with AgNO3 is not redox reaction. It is a precipitation reaction.
