What is the basicity of H3PO3 justify your answer?
2
Since there are two ionizable hydrogen groups in \[{H_3}P{O_3}\] , hence the basicity of this acid is 2.
What is the basicity of H 3 PO 3 and H3PO4?
H3PO4 has three ionizable hydrogen atoms. Hence, its basicity is 3….The p-Block Elements.

What is the basicity of H3PO2?
1
H3PO2:Basicity of H3PO2 is 1 due to availability of only 1 H with O atom which can be released in the aqueous solution.
What is the basicity of H3PO4 and h2so4?
In these two figures we can easily see that there are 3 –OH groups in phosphoric acid and 2 –OH groups in sulphuric acid. Hence Basicity of ${H_3}PO_4^{}$ is 3 and ${H_2}S{O_4}$ is 2 and polybasic acids are those which have basicity equal to two or greater than two. Therefore, they both are polybasic acids .
What is the equivalent mass of H3PO4?
49
The equivalent mass of phosphoric acid (H3PO4) is 49 .
What is the basicity of Hcooh?
Even though it has two hydrogen atoms, only one hydrogen is ionizable to produce hydronium ion. Thus its basicity is 1.
What is the equivalent weight of H3PO3?
Equivalent weight = M / 2, since no. of replaceable H+ ions in H3PO3 = 2. Hence, If the molecular weight of H3PO3 is M, its equivalent weight will be M / 2. The number of replaceable or ionisable hydrogen atoms in an acid is the hydrogens attached to the oxygen atom.
Is H3PO3 strong or weak?
Weak. The equilibrium constant for the dissociation of phosphoric acid is 6.9×10⁻³. A “strong” acid is one that (nearly) completely dissociates.
What is the basicity of phosphorous acid H3PO3?
Phosphorous acid (H3PO3) forms salts known as phosphites which are sometimes used as reduction agents. For hydrogen to be acidic it must be attached to a strongly electronegative atom. It has two P−OH bonds and one P−H bond. Hence, its basicity is 2.Here it is attached to 2 oxygen Hence basicity of H3PO3 is 2.
How many hydrogen atoms are present in H3PO3?
Though H3PO3 has 3 Hydrogen but its basicity is 2 because 2 hydrogens are released as H+ (H3O+)ion in aquous soluton .The third one is directly bonded to Phosphorous. two. it has only two replaceable hydrogen atom attached to OH group in its http://structure.so basicity is two.
What is the formula for H3PO4?
H3PO4, phosphoric acid, can be written O=P(OH)3. It has three acidic protons (attached to oxygen) and is therefore tribasic. Its salts are called phosphates. But H3PO3, phosphonic acid, has one of the hydrogens directly bound to phosphorus as O=PH(OH)2.
Why is H3PO3 a dibasic acid?
But H3PO3, 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. Its salts are called phosphonates. There is also an H3PO3, phosphorous acid P (OH)3, that is tribasic. Its salts are called phosphites. Simply H3PO3 is dibasic or with basicity 2.
