Question

The normality of 03M phosphorus acid (H2PO2) is​

Answer 1

Answer:

when you will study chemical bonding in chemistry then you will learn some concept which will help you in determining and n factor.

and that n factor will help you to obtain normality out of molarity and n factor.

one such concept is that

when the side atoms are Oxygen and there is a charge over a compound then that charge goes along with oxygen

and if the sides atom is not oxygen then the charge goes along the least electronegative element present in the compound.

the picture given above shows the arrangement of molecules in in H2PO2 ion or H2PO3 molecule.

H2PO2 to exist as form of of charged compound having a charge of -1.

one more concept of chemical bonding is that only the hydrogen which is connected with oxygen will decide the n factor of compound.

so as you could see that there is only one hydrogen which is connected to oxygen

the n factor of the compound becomes 1

normality = n factor x molarity

normality= 1x 03M = 3M
