Question

Family of salts have:
A. Common acidic radicals
B. Common basic radicals
C. Both A and B
D. Common physical properties

Answer 1

Hint:- Family of salts means those salts which have some part of the salt the same or in other words we can say that some element of the salt is the same in all the salts which belong to the same family.

Complete answer:
As we know that cation is a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis.
And anion is an ionic species having a negative charge. They are atoms that have gained electrons. And anions are attracted to the anode in electrolysis.
As we know that the salt is a chemical compound consisting of an ionic assembly of cations and anions. Salts are composed of related numbers of cations and anions so that the product is electrically neutral.
Or we can say that salt is the chemical compound consisting of acidic and basic radicals. Where anion is acidic radicals and cation is the basic radicals.
So, if the two salts have the same positive or negative radical then they belong to the same family.
Like, Sodium chloride (NaCl) and Calcium Chloride $\left( {CaC{l_2}} \right)$ have the same acidic radical (Cl). So, they belong to the same family of salt.
And, Calcium Chloride $\left( {CaC{l_2}} \right)$ and Calcium Sulphate $\left( {CaS{O_4}} \right)$ have same basic radical (Ca). So, they belong to the same family of salt.
So, we can say that families of salts should have common acidic radical or common basic radical.

Hence, the correct option will be C.

Note:- Whenever we come up with this type of problem, we should remember that in any compound the positive ion is known as cation and is the basic radical of the compound whereas the negative ion is known as anion and is an acidic radical of the compound. So, the salts belonging to the same family of salts should have acidic radical common or basic radical common.
