(1) NaCl, KCl, Na2SO4, NaNO3
(2) NaCl, Na2SO4, MgSO4, Na2SO3
(3) KCl, MgCl2, NaCl, Na2SO4
(4) Na2SO4, NaCl, NaNO3, CH3COONa

Answer 1

Which of the following groups contains the salts of same family?

(1) NaCl, KCl, Na2SO4, NaNO3 ❌

(2) NaCl, Na2SO4, MgSO4, Na2SO3 ❌

(3) KCl, MgCl2, NaCl, Na2SO4 ✔

(4) Na2SO4, NaCl, NaNO3, CH3COONa❌

Answer 2

Answer: Option (1) is the correct answer.

Explanation:

When a salt contains same acidic or basic radicals then it means they belong to the same family.

For example, NaCl and KCl belong to chloride family.

Whereas $Na_{2}SO_{4}$ and $NaNO_{3}$ belong to sodium family.

In the other options, all salts belong to different families and they do not exist in pairs.

Hence, we can conclude that NaCl, KCl, $Na_{2}SO_{4}$, and $NaNO_{3}$ groups contains the salts of same family.
