Question

what is the valency of HNo3

Answer 1

+1(of h)+5(N)-6(of O*3)

SO YOUR ANSWER WILL BE 0

AS VALENCY IS THE COMBINIG CAPACITY AND THIS IS NOT APPLICABLE FOR COMPOUNDS

Answer 2

Valency of$HNO_3$ is 0.

Explanation:

• $HNO_3$ is chemically called Nitric acid has the molecular weight of 63 grams, is composed of three elements namely Hydrogen, Nitrogen, Oxygen which are having valencies +1, +5, -2 respectively.

• There is one hydrogen atom, one nitrogen atom and three oxygen atoms in the$HNO_3$. Here the valency of the nitrogen will be +5.

• Because, losing 5 electrons will be easier than gaining 3 electrons as it also has H and O beside it.

• So the valency of$HNO_3$ (Nitric Acid) is 0, by ((1(1))+(1(5))+(3(-2))).

• We did this by adding all the valencies of the individual elements by multiplying those with the corresponding number of elements.
