Question

Among P2O5, As2O3, Sb2O3 and Bi2O3, the most acidic oxide is (A) P2O5 (B) As2O3 (C) Sb2O3 (D) Bi2O3

Tardigrade Admin · Accepted Answer

P 2 O 5, As 2 O 3 are acidic oxides, Sb 2 O 3 is an amphoteric while Bi 2 O 3 is basic oxide but P 2 O 5 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.

Q. Among $P_{2} O_{5}, A s_{2} O_{3}, S b_{2} O_{3}$ and $B i_{2} O_{3}$ , the most acidic oxide is

$P_{2} O_{5}$

$A s_{2} O_{3}$

$S b_{2} O_{3}$

$B i_{2} O_{3}$

Q. Among P2​O5​,As2​O3​,Sb2​O3​ and Bi2​O3​, the most acidic oxide is

P2​O5​

As2​O3​

Sb2​O3​

Bi2​O3​

P2​O5​,As2​O3​ are acidic oxides, Sb2​O3​ is an amphoteric while Bi2​O3​ is basic oxide but P2​O5​ 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.

Q. Among $P_{2} O_{5}, A s_{2} O_{3}, S b_{2} O_{3}$ and $B i_{2} O_{3}$ , the most acidic oxide is

$P_{2} O_{5}$

$A s_{2} O_{3}$

$S b_{2} O_{3}$

$B i_{2} O_{3}$
