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:
Positive Radicals- Hydrogen,Sodium
Basic Radicals-For example the decomposition of HCl form H+ and chloride ion. ... Here cation is known as basic radical. Some common examples of basic radicals are Na+, Ba2+, Fe3+ etc.
Composite Radicals-Acetylimino, Cyclohexane carbonyl etc.
Metal with Variable Valency-IRON
COPPER
MERCURY
SILVER
TIN
Bivalent Acidic Radicals-The ion formed after removal of Hydrogen ion from an acid is called as Acidic Radical.
For example:
when HCl loses H⁺ ion from acid . we get Cl⁻ which is an acidic radical -- which is monovalent.
Bivalent means the acid should lose 2 H+ ions.
example:
H2SO4 :
From H2SO4 loses 2 H⁺ ions, so we get, SO₄⁻²
Carbonic acid.
H2CO3
H2CO3 loses 2H⁺ ions we get CO₃⁻²
Trivalent Basic Radicals-Some example are as Examples of Trivalent basic radicals are: HCI ( acid), CI- (acid radical),HNO3 (acid), NO2 ( ACID)
