Answer:
False
Explanation:
Redox reaction is defined as the chemical reaction that includes both reduction and oxidation of atoms through the transfer of electrons between two reactants participating in it.
The given chemical equation: NaNO2 + HCl —> NaCl + HNO2 is a double displacement reaction and not a redox reaction because there is no change in the oxidation number of two of the atoms in the reaction. While the reactant ions exchange places to form new products through double displacement reaction.
Hence, the given equation is not a redox reaction but a double displacement reaction.
The reaction NaNO2 + HCl —> NaCl + HNO2 is not a redox reaction.
A redox reaction is a reaction in which there is a change in the oxidation number of the reactants from left to right. Hence, in a redox reaction, the oxidation number of species either increases or decreases as we move from left to right.
In the reaction NaNO2 + HCl —> NaCl + HNO2, the oxidation number of each specie remains the same from left to right hence, it is not a redox reaction.
