Law of equivalence states that
One equivalent of an element combines with one equivalent of the other.
Equivalent of Na is 22.99 and that of O is 8. By the law of equivalence, 1 equivalent of Na combines with 1 equivalent of O. But in NaX2OX2, 23×2 parts by weight of sodium combines with 16×2 parts by weight of oxygen⟹23 parts by weight of sodium combines with 16 parts by weight of oxygen which means one equivalent of sodium combines with two equivalents of oxygen which is contradiction to law of equivalence. So why does this compound not follow the law of equivalence?
