Question

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

Answer 1

Explanation:

According to Arrhenius, bases are the species which when dissolved in water will give hydroxide ions, that is, $OH^{-}$.

On the other hand, species which tend to dissociate in water to given hydrogen ions, that is, $H^{+}$ ions are known as acids.

So, in the given situation $NO^{-}_{2}$ is the anion. And, when when it is added to water the it will combine with a hydrogen atom and results in the formation of $HNO_{2}$.

The reaction equation will be as follows.

   $NO^{-}_{2}(aq) + H_{2}O(l) \rightarrow HNO_{2}(aq) + OH^{-}(aq)$

Answer 2

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)
