Question

Which of the following is not an example of redox reaction?

${ CuO + H2 \rightarrow Cu + H2O}$

${ Fe2O3 + 3CO \rightarrow 2Fe + 3CO2 }$

${ 2K + F2 \rightarrow 2KF}$

${ BaCl2 + H2SO4 \rightarrow BaSO4 + 2HCl}$

Answer

${ BaCl2 + H2SO4 \rightarrow BaSO4 + 2HCl}$

Explanation

Solution

${BaCl2 + H2SO4 \rightarrow BaSO4 + 2HCl}$ is not a redox reaction as it does not involve any change in oxidation number. It is an example of double decomposition reaction.
