Reactivity towards oxygen: All froup 15 elements from two types of oxides: E2O3 and E2O5. 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 E2O3 of nitrogen and phosphorus are purely acidic, that of arsenic and antimony are amphoteric and those of bismuth predominantly basic.
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…
