Find the equivalent weight of HNO3 in P+ HNO3 =>HPO3 + NO +H2O​

Answer 1

Explanation:

How can I calculate the equivalent weight of HNO3?

Master's certification in external aerodynamics simulations.

HNO3 is an acid and an oxidising agent. As a monoprotic acid its equivalent weight is 63, i.e., equal to the molecular weight.

As an oxidising agent its equivalent weight depends on the product. In a redox reaction HNO3 can reduce to any of the following: NO, NO2, N2O, etc depending on the concentration of the acid and the reducing agent. In these cases the equivalent weight is given by Molecular weight/ change in oxidation number of N atom.
