or NO2−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 in your answer.

Respuesta :

Answer : The chemical reaction will be:

[tex]NO_2^-(aq)+H_2O(l)\rightleftharpoons HNO_2(aq)+OH^-(aq)[/tex]

Explanation :

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions [tex](OH^-)[/tex] when dissolved in water and an acid is defined as a substance which donates hydronium ions [tex](H_3O^+)[/tex] in water.

As per question, when [tex]NO_2^-[/tex] react with water then it combine with hydrogen of water and gives [tex]HNO_2[/tex] and [tex]OH^-[/tex] as a product.

The chemical reaction will be:

[tex]NO_2^-(aq)+H_2O(l)\rightleftharpoons HNO_2(aq)+OH^-(aq)[/tex]
