Which of the following oxides is most acidic ?

A

`Bi_2 O_3`

B

`P_2 O_3`

C

`As_2 O_3`

D

`Sb_2O_3`

Text Solution

Verified by Experts

The correct Answer is:
B
Type of oxide remaining the same, `M_2 O_3` with the increase in electronegativity, acidic character increases, hence `P_2 O_3` is most acidic.
`(EN of P gt As gt Sb gt Bi)`.
