Question

valency of KNO3 and KNO2
I will mark the first answer as brainliest​

Answer 1

Answer:

KNO3 & KNO2:

K+ has a charge of +1

NO3 -1 has the charge of -1

The NO3–1 ion contains a nitrogen with Charge +5 and three oxide ions each having a charge of -2

3(-2) + 5. =-1

Answer 2

Answer:

As a neutral compound it has no valency as a salt.

However it's components do have a valence.

K+ has a charge of +1

NO3 -1 has the charge of -1

The NO3–1 ion contains a nitrogen with Charge +5 and three oxide ions each having a charge of -2

3(-2) + 5. = -1
