Question

Which of the followingis the most acitic oxide p2o5, as2o3, sb2o3?

Answer 1

Explanation:

The elements P, As, and Sb belongs to the same group. When we move down the group, then there is increase in the size atoms. As a result, there will be decrease in the electronegativity of atoms.

Hence, metallic character and basicity of these elements increases. Therefore, there will be decrease in acidic strength on moving down the group.

Thus, we can conclude that out of the given options, $P_{2}O_{5}$ is the most acidic and $Sb_{2}O_{3}$ is the least acidic in nature.
