Question

what is the n factor of H3PO3

Answer 1

The H atoms which are linked to oxygen are replaceable,but H atom linked directly to central atom P is nonreplaceable.Therefore n factor forH3PO3 is 1 or 2.

Answer 2

Answer:

As $H_{3}PO_{3}$ is an acid so, n- factor of $H_{3}PO_{3}$ is 1 or 2

Explanation:

n - factor of acids = Number of $H^{+}$ ions in the solution

Some Examples of n- factor in acids are :--

• n-factor of $H_{2}SO_{4}$ = 1 or 2 because it can transfer max 2 $H^{+}$
