Which of the following oxide is most acidic?

A
$\mathrm{As}_2 \mathrm{O}_3$
Correct answer
B
$\mathrm{P}_2 \mathrm{O}_5$
C
$\mathrm{Sb}_2 \mathrm{O}_3$
D
$\mathrm{Bi}_2 \mathrm{O}_3$

Solution

More be the positive oxidation state of a non-metallic oxide, more be its acidic nature. $\therefore \mathrm{P}_2 \mathrm{O}_5$ is most acidic.

Hence, the correct answer is option: 'B'.
