Question

Given below are two statements :

Statement I: The pentavalent oxide of group- $15$ element, $E_{2} O_{5}$ , is less acidic than trivalent oxide, $E_{2} O_{3}$ , of the same element.

Statement II : The acidic character of trivalent oxide of group $15$ elements, $E_{2} O_{3}$ , decreases down the group.

In light of the above statements, choose most appropriate answer from the options given below

TestHub · Accepted Answer

Reactivity towards oxygen: All froup 15 elements from two types of oxides: E 2 O 3 and E 2 O 5 . The oxide in the higher oxidation state of the element is more acidic than that of lower oxidation state. Their acidic character decreases down the group. The oxides of the type E 2 O 3 of nitrogen and phosphorus are purely acidic, that of arsenic and antimony are amphoteric and those of bismuth predominantly basic.
