Question

Anhydride of an acid X contains 2 phosphorus atoms and 5 oxygen atoms.If this acid X is made to react with bases,like ,sodium hydroxide,what will be the formulae of the corresponding normal salts formed?​

Answer 1

Answer:

Na3PO4 or Na2HPO3 or NaH2PO2

Answer 2

$\huge\bf{Answer:}$

(i) Identification of X from the respective anhydride.

(ii) Predicting the formulae of the bases based on nomenclature.

(iii) Nature of reaction between acid X and respective bases.

(iv) Predicting the valency of negative redical inX.

(v) Predicting the valency of sodium, calcium and aluminium respectively.

(vi) Applying crisscross method to determine formulae of the corresponding salts.
