(a) Write the dissolution reaction for solid Na2CO3 below. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answer.)

(b) Once the ionic solid has dissolved, the anion that is formed is able to react as a base, with water as the acid. Write the net acid-base reaction that occurs when dissolved Na2CO3 reacts with water. (Use the lowest possible coefficients. Omit states-of-matter in your answer.)

Answer:

For a: The chemical equation for the dissolution of sodium carbonate is [tex]Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)[/tex]

For b: The net acid-base reaction is [tex]CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)[/tex]

Explanation:

  • For a:

Dissolution reaction is defined as the reaction in which a solid compound gets dissolved in water to form aqueous solution.

The chemical equation for the dissolution of sodium carbonate follows:

[tex]Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)[/tex]

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

The chemical equation for the ionization of sodium carbonate follows:

[tex]Na_2CO_3(aq.)\rightarrow 2Na^+(aq.)+CO_3^{3-}(aq.)[/tex]

  • For b:

Now, the anion formed which is [tex]CO_3^{2-}[/tex] reacts with water to form conjugate acid.

The chemical equation for the reaction of anion with water follows:

[tex]CO_3^{2-}(aq.)+H_2O(l)\rightarrow OH^-(aq.)+HCO_3^-(aq.)[/tex]

Hence, the net acid-base reaction of the anion formed and water is written above.

(a) The chemical equation for the dissolution of sodium carbonate is

[tex]Na_2CO_3(s)---- > Na_2CO_3(aq)[/tex]

(b) The net acid-base reaction is

[tex]CO_3^{2-}(aq)+H2O(l)---- > OH^-(aq)+HCO_3^-(aq)[/tex]

Dissolution reaction:

The Dissolution reaction is defined as the reaction in which a solid compound gets dissolved in water to form an aqueous solution.

The chemical equation for the dissolution of sodium carbonate follows:

[tex]Na_2CO_3(s)---- > Na_2CO_3(aq)[/tex]

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in an aqueous solution.

The chemical equation for the ionization of sodium carbonate follows:

[tex]Na_2CO_3(aq)---- > 2Na^+(aq)+CO_3^{2-}(aq)[/tex]

(b)

Now, the anion formed which reacts with water to form conjugate acid.

The chemical equation for the reaction of the anion with water follows:

[tex]CO_3^{2-}(aq)+H2O(l)---- > OH^-(aq)+HCO_3^-(aq)[/tex]
