p-Block elements form acidic, basic and amphoteric oxides. Explain each property by giving two examples and also write the reactions of these oxides with water.
ACIDIC OXIDES
SO2, B2O3 are acidic oxides and p block elements.
The reaction of SO2 with water
SO2 + H2O → H2SO3
The reaction of B2O3 with water
B2O3 +3 H2O → 2H3BO3
Acidic oxides are those oxides that form acids after reacting with water.
BASIC OXIDES
Cao, BaO, Ti2O form basic oxides
The reaction of Ti2O with water.
BaO + H2O → Ba(OH)2
REACTION OF CaO WITH WATER
Cao + H2O → Ca(OH)2
Basic oxides are those oxides that form bases after reacting with water
AMPHOTERIC OXIDES
Zinc oxides and aluminium oxides are the two amphoteric oxides.
Reaction of ZnO with water:
ZnO + 2H2O + 2NaOH → Na3Zn[OH]4 + H2
ZnO +2HCl → ZnCl2 + H2O
Reaction of Al2O3 with water:
Al2O3 (s) + 6 NaOH(aq) + 3H2O(l) → Na3 [Al(OH)6] (aq)
Al2O3 (s) + 6HCl(aq) + 9H2O(l) → 2[Al(H2O)]3+(aq) + 6Cl-
