Question

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 1

Answer: NaCl, kCl, NaCl, Na2SO4, NaNO3 CH3COONa( cations of first group)

MgCl2, MgSO4( cations of 2nd group in the periodic table)

Explanation:

(1) Because all these are the salts which have cations is Na  which belongs to first group of the periodic table.

(2) And in these, all cations (Mg) in salts belong to second group.

Answer 2

Answer:

Answer - Option 1

Explanation:

When the salt contains the same acidic or the basic radicals then it means the groups belong to same family of salts.

For example, $NaCl$ and $KCl$ belong to the chloride family.

Whereas $Na_2SO_4$ and $Na_2NO_3$ belong to the sodium family.

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

Hence, we can conclude that (NaCl, KCl) and ($Na_2SO_4$, $Na_2NO_3$) groups contains the salts of same family.
