Question

7. Of the following, choose the correctly represented Parent acid and Parent base of Sodium Sulphate?

A. Sulphuric acid and Sodium Hydroxide.

B. Hydrochloric acid and Sodium Hydroxide.

C. Sulphuric Acid and Magnesium hydroxide.

D. Sulphuric acid and Calcium Hydroxide.

which option is correct.​

Answer 1

Answer:

A

Explanation:

As Sodium Sulphate is Na2SO4 when we separate parent base and parent acid it will be- Parent base- NaOH Parent Acid-H2SO4

Answer 2

Among the following, the parent acid and parent base of sodium sulphate are sulphuric acid and sodium hydroxide. Thus, the correct option is A.

Explanation:

• When sodium hydroxide (base) is reacted with sulphuric acid (acid), it results in the formation of sodium sulphate.
• The reaction is given as:

         $\[2NaOH + {H_2}S{O_4} \to N{a_2}S{O_4} + 2{H_2}O\]$

• As sodium sulphate is formed by the reaction of sulphuric acid and sodium hydroxide, therefore, the parent acid and the parent base are sulphuric acid and sodium hydroxide.
