(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.)

<u>Answer:</u>

<u>For a:</u> The chemical equation for the dissolution of sodium carbonate is Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)

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

<u>Explanation:</u>

  • <u>For a:</u>

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:

Na_2CO_3(s)\rightarrow Na_2CO_3(aq.)

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:

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

  • <u>For b:</u>

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

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

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

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

What is the pH of a solution with hydrogen ion concentration of 1 x 10^–6 M?
kakasveta [241]

Answer:

The pH of the solution is 6,00.

Explanation:

The pH indicates the acidity or basicity of a substance. pH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as:

pH = -log (H +)

pH= -log (1x10^-6)

<em>pH= 6, 00</em>

Which three groups of the periodic table contain the most elements classified as metalloids (semimetals)?
attashe74 [19]
The metalloids are mostly concentrated in groups 14, 15, and 16. (Some simpler charts will show them as 4A, 5A, and 6A - take a look at the top of the periodic table your class uses to double-check).
