The redox reaction among the following is
The redox reaction among the following is
Options
- A\text{2}\text{NaOH}\text{+}{\text{Cl}_{2} \to \text{NaCl}\text{+}\text{NaOCl}\text{+}{H}_{2} \text{O}
- Bformation of ozone from atmospheric oxygen in the presence of sunlight
- Creaction of [ \text{Co} ( {H}_{2}O{)}_{6} ] \text{C}{\text{l}_{3} with \text{AgN}{\text{O}_{3}
- Dreaction of {H}_{2}\text{S}{\text{O}_{4} with
Correct answer
A. \text{2}\text{NaOH}\text{+}{\text{Cl}_{2} \to \text{NaCl}\text{+}\text{NaOCl}\text{+}{H}_{2} \text{O}
Step-by-step solution
\text{2}\text{NaOH}\text{+}{\text{Cl}_{2} \to \text{NaCl}\text{+}\text{NaOCl}\text{+}{H}_{2} \text{O}
Here {\text{Cl}_{2} is undergoing oxidation as well as reduction.In rest of these reactions oxidation states are not changing so these are not redox reactions.
\text{2NaOH} + {H}_{2}\text{S}{\text{O}_{4} \to \text{N}{\text{a}_{2}\text{S}{\text{O}_{4} + \text{2}{\text{H}_{2}O
Ag\text{N}{\text{O}_{3} + \text{NaCl} \to \text{NaN}{\text{O}_{3} + \text{AgCl}
Here {\text{Cl}_{2} is undergoing oxidation as well as reduction.In rest of these reactions oxidation states are not changing so these are not redox reactions.
\text{2NaOH} + {H}_{2}\text{S}{\text{O}_{4} \to \text{N}{\text{a}_{2}\text{S}{\text{O}_{4} + \text{2}{\text{H}_{2}O
Ag\text{N}{\text{O}_{3} + \text{NaCl} \to \text{NaN}{\text{O}_{3} + \text{AgCl}
