How do the acidic properties change in the series of the following compounds n2o5 – p2o5

How do the acidic properties change in the series of the following compounds n2o5 – p2o5 – as2o5 – sb2o5 – bi2o5? why?

To begin with, let’s recall some patterns of changes in the properties of elements (as well as higher oxides) in the periodic table.

In periods from left to right, as well as in groups (main (A) subgroups) from bottom to top
-EO increases
-increases acidic properties
-the radius of the atom decreases
– the basic properties are weakened

Now we will find where the elements that form oxides in the row are located – this is the 5A group

In the table, the elements are specially arranged so that these properties have regularities. Acid properties depend on the degree of oxidation (highest = group number) and also on the radius of the atom (the more, the weaker the acidic properties because the ability to give an electron from the outer electron shells increases).

Therefore, in the range from N to Bi, the acidic properties will weaken.
