p-Block elements form acidic,

Solution:

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-
