Question

25. @Which of the following salts belong to the same family of salts?

I) sodium chloride and sodium acetate

(II) calcium sulphate, magnesium sulphate

iii) sodium carbonate and sodium hydrogencarbonate

(IV) sodium chloride and magnesium sulphate

(a) Both (l) and (II)
(b) Both (l) and (IlI)
(c) (i), (II) and (III)
(d) (I), (III) and (IV)​

Answer 1

Answer:

d answer

Explanation:

because it has salts belong same family of salts

Answer 2

Option C is the correct answer.

• Generally, Salts can differ either by having a different anion or by having a different cation.
• Two Salts having the same cation but different anion belongs to the same cation salt family.

• Two Salts having the same anion but different cation belongs to the same anion salt family.

From the given options:

I) sodium chloride and sodium acetate,

• Cations: Sodium and Sodium.
• Anions: Chloride and acetate.

Hence they belong to the Sodium salt family.

II) Calcium sulfate and Magnesium Sulfate,

• Cations: Calcium and magnesium.
• Anions: Sulfate and Sulfate.

Hence they belong to the Sulfate salt family.

III) sodium carbonate and sodium hydrogen carbonate,

• Cations: Sodium and Sodium.
• Anions: carbonate and hydrogen carbonate.

Hence they belong to the Sodium salt family.

IV) sodium chloride and magnesium sulfate,

• Cations: Sodium and magnesium.
• Anions: Chloride and sulfate.

They do not belong to the same salt family because the cations and anions are not the same. Hence they do not belong to the same family of salts.

Hence, (I), (II), and (III) belong to the same family of salts.

Therefore Option C is the correct answer.
