Answer:
Explanation: The reaction NaNO3 -> Na+ + NO3- is not a redox reaction.
In a redox reaction, there is a transfer of electrons from one species to another. To determine if a reaction is redox or not, we can assign oxidation numbers to each element in the reactants and products.
In NaNO3, sodium (Na) has an oxidation number of +1, nitrogen (N) has an oxidation number of +5, and oxygen (O) has an oxidation number of -2.
In the products, Na+ has an oxidation number of +1 and NO3- has an oxidation number of -1 for nitrogen (N) and +2 for each oxygen (O).
When we compare the oxidation numbers of the elements in the reactants and products, we can see that the oxidation numbers of Na, N, and O remain the same. There is no change in the oxidation numbers, indicating that there is no transfer of electrons and therefore, it is not a redox reaction.
To summarize:
- The reaction NaNO3 -> Na+ + NO3- is not a redox reaction.
- The oxidation numbers of Na, N, and O remain the same in both the reactants and products.
- There is no transfer of electrons in this reaction.
