For no2−, write an equation that shows how the anion acts as a base. express your answer as a chemical equation. identify all of the phases i

Hello!

Bases are defined by Arrhenius as substances which release OH⁻ ions when dissolved in water. NO₂⁻ complies with this definition by the chemical reaction that is shown below:

NO₂⁻(aq) + H₂O (l) HNO₂ (aq) + OH⁻(aq)

The chemical reaction in which NO2^- acts as a base is; H3O^+(l) + NO2^- (aq) ------> HNO2(aq) + H2O(l)

According to the Brownstead - Lowry definition of acids and bases, an acid is any substance that donates a proton while a base is any substance that accepts a proton. Hence, the NO2^- ion acts as a base in reactions where it accepts a proton to yield its conjugate acid.

In the reaction; H3O^+(l) + NO2^- (aq) ------> HNO2(aq) + H2O(l), we can see that the NO2^- accepted a proton from H3O^+ to yield its conjugate acid HNO2.
