Question

b) Classify the into acidic, basic and Amphoteric
orides.

i) CO2 ii) Al 203 ii) k 20 iv) SO2 v) ZnO
vi) Na 20​

Answer 1

Explanation:

(I)CO2 is an acidic oxide..it reacts with water to form carbonic acid.

CO2+H2O-->H2CO3(carbonic acid)

(ii) Al2O3 is an amphoteric oxide..it reacts with both acids and bases to produce water and salt..

with acid: Al2O3+6HCl-->2AlCl3+3H2O

with base:Al2O3+2NaOH-->2NaAlO2+H2O

(iii) K2O is basic oxide..it is a strong base..

K2O+H2O-->K2(OH)2

(iv) SO2 is an acidic oxide.. it reacts with water to form sulphurous acid

SO2+H2O-->H2SO3(sulphurous acid)

(v) ZnO is an amphoteric oxide.. it reacts with both acids and bases to form salt and water

with acid:ZnO+2HCl--> ZnCl2+H2O

with base:ZnO+2NaOH-->2Na2ZnO2+H2O

(vi) Na2O is a basic oxide... it reacts with water to form basic sodium hydroxide

Na2O+H2O-->2NaOH

Hope it helps you..

thank you
