Among P2O5, As2O3, Sb2O3 and Bi2O3, the most acidic oxide is(a) P2O5(b

1.	Among P2O5, As2O3, Sb2O3 and Bi2O3, the most acidic oxide is(a) P2O5(b) As2O3(c) Sb2O3(d) Bi2O3
Answer» Answer is : (a) P₂O₅ P₂O₅, As₂O₃ are acidic oxides, Sb₂O₃ is an amphoteric while Bi₂O₃ is basic oxide but P₂O₅ is most acidic among them all. This is because down the group, metallic character increases and metal oxides are more basic, thus the basicity of metallic oxides also increases.

Answer»

Answer is : (a) P₂O₅

P₂O₅, As₂O₃ are acidic oxides, Sb₂O₃ is an amphoteric while Bi₂O₃ is basic oxide but P₂O₅ is most acidic among them all. This is because down the group, metallic character increases and metal oxides are more basic, thus the basicity of metallic oxides also increases.
