b. Basic Radical : Na+, Fe2+,Ag+, Al3+,Cr3+,Fe3+,Au3+,Co2+,Ni2+,Hg2+,Sn2+.

c. Composite Radical : SO4 2- ,NH4+ ,HCO3- , HSO4- , NO4-.

d. Metal With Variable Valency : Cu(1+,2+), Hg(1+,2+) ,Fe(2+,3+).

e. Bivalent Acidic Radical : S2- ,O2- ,Se2- .

f. Trivalent Basic Radical : Al3+ ,Cr3+,Fe3+,Au3+.

Answer 2

The positively charged part of a salt (cation) which has been derived from a base is known as “ basic radical ”


The negatively charged part of the salt (anion) which has been derived from an acid is known as “acidic radical”

Example:
Salt Magnesium chloride is obtained by action of acid HCl and base Mg(OH)

​
.
Thus Mg
+2
ion is basic radical and Cl
−
is acidic radical.

2HCl+Mg(OH)
2
​
→MgCl
