Question

If in a reaction HNO3 is reduced to NO, the mass of HNO3 absorbing 1 mole of
electron would be
a) 12.6gm (6) 21 gm (c) 31.5 gm (d) 63.0 gm​

Answer 1

$\huge{\pink{\red{\sf \boxed{Answer}}}}$

We have HNO3---->NO

The change in oxidation number is +3

Equivalent mass of HNO3 =(1+14+16+16+16+16)/3=63/3

=2l g (around

Hence, Option (b) is answer.
