Question
Chemistry Question on properties of d block elements
Identify the set of acidic oxides.
A
Na2O,CaO,BaO
B
ZnO,PbO,BeO
C
CO,NO,N2O
D
Mn2O7,CrO3,V2O5
Answer
Mn2O7,CrO3,V2O5
Explanation
Solution
Acidic oxides →Mn2O7,CrO3,V2O5
(due to higher oxidation state of central metal) Basic oxide →Na2O,CaO,BaO
(due to lower oxidation state of central metal) Alkaline and alkali metal oxide are always basic. Neutral oxides →CO,NO,N2O
Amphoteric oxides →ZnO,PbO,BeO (acidic as well as basic)
