Question

What is the normality of 2M H3PO2 solution?

Answer 1

Normality = Molarity / Basicity

Basicity of H3PO2 is 1

Therefore for H3PO2,

Normality = Molarity

Normality of 2M H3PO2 is 2N

Answer 2

Answer: 2N

Explanation: Normailty is defined as number of gram equivalents present per litre of the solution.

$Normality=Molarity\times n$

n= basicity= number of replaceable hydrogen

For $H_3PO_2$ , n=1 as there is only one replaceable hydrogen as only one hydrogen is attached to electronegative oxygen.

$Normality=2M\times 1=2N$
