Write the oxyacids of the following: Oxide Oxyacids N 2 O 3 NO 2 / N 2 O 4 N 2 O 5 P 4 O 6 P 4 O 10

An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H + cation and the anion of the acid. N 2 O 3 + H 2 O → 2 HNO 2 N 2 O 4 + H 2 O → HNO 2 + HNO 3 N 2 O 5 + H 2 O → 2 HNO 3 P 4 O 6 + H 2 O → 4 H 3 PO 3 P 4 O 10 + 6 H 2 O → 4 H 3 PO 4

decomposition of P 2 H 4 at 110 ° C .

heating red phosphorus with an aqueous solution of caustic soda.

What is inert pair effect?

The inert pair effect is the reluctance of s electrons of the outermost shell to participate in bonding. This is due to the poor screening effect of the d and f orbitals. This effect is observed among the p -block elements, due to which the lower oxidation state (two units less than the group oxidation state) becomes more stable for heavier elements in each group. For example in Pb , + 2 oxidation state is more predominant than the + 4 oxidation state.
