Question

find the N factor of H3PO4 H3PO2 H3PO3

Answer 1

N factor of H3PO4 is 3
N factor of H3PO3 is 2
N factor of H3PO2 is 1
H3PO4  ---- 3$H^{+} +PO4 ^{-3}$
H3PO3---$2 H^{+}+HPO3 ^{-2}    H3PO2 -- H^{+}+H2PO2 ^{-1}$

Answer 2

Answer:

1. N factor of $H_{3} P O_{4}$ is 3
2. N factor of $H_{3} P O_{3}$ is 2
3. N factor of $H_{3} P O_{2}$ is 1

Explanation:

Acids are components which releases H+ ions, ions formed when dissolved in a solvent. For acids, the n factor definition is the number of the H+ ions which replaces or moves them by a single mole of Acid by quantity in the reaction.

It should be kept in the mind that the n-factor the acid is not equal to the basicity of compound; i.e. number of interchangeable moles of hydrogen positive atom present in single mole of acid.
