Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. In H 3 PO 3 there are two O-H bonds, connected to phosphorus. It is a colorless or yellowish solid with a garlic like taste. Answer: It is monobasic. H 3 PO 4, phosphoric acid, can be written O=P(OH) 3.It has three acidic protons (attached to oxygen) and is therefore tribasic. When this reacts with NaOH one Na+ ions replaces the H in the only OH group and the other two H atoms (bonded directly to the P atom ) are not replaced.

Phosphorous acid dissociates to form dihydrogen phosphite and hydronium ion. Explanation: Ortho Phosphorous acid is an acid as it dissolves in water to form hydrogen ions. IIT JEE 2003: For H3PO3 and H3PO4, the correct choice is (A) H3PO3 is dibasic and reducing (B) H3PO3is dibasic and non-reducing (C) H3PO4is tribasic Check Answer and Solution for above question AIIMS 2003: The true statement for the acids of phosphorus, H3PO2, H3PO3 and H3PO4 is (A) the order of their acidity is H3PO4 > H3PO3 > H3PO2 (B) all It is monobasic means it donates oe ions when dissolved in water though it contains two hydrogen atoms.. Only those atoms which are attached to O in P-OH form are ionisable and are responsible for the basicity. The P-H bond in H3PO3 is not ionisable and do not play any role in its basicity. Join now.

Give two examples of each of the following: monobasic acid. Hence NaH2PO2. Which of the following is not a monobasic acid? Formula H3PO3.Because it can form Phosphite salts containing PO3-3 anions.But its structure is not like Boric acid(H3BO3) kPa1: 2.16 kPa2: 7.21 . But H 3 PO 3, phosphonic acid, has one of the hydrogens directly bound to phosphorus as O=PH(OH) 2.This means that only two hydrogens are available to act as acids. ← Prev Question Next Question →.
