Question

Assuming 100% ionization,the solution having highest normality?

1) 1 M H₂SO₄
2) 1 M H₃PO₃
3) 1 M H₃PO₄
4) 1 M HNO₃
Answer ASAP

Answer 1

Since molarity is equal to molarity * n factor
So the acid having highest n factor will have the highest normality
So in this case.. It will be H3Po4 coz it has n factor of 3
Hn03. 1
H2so4. 2
H3po3. 2
Hoep it helps

Answer 2

First of all we should write the basicity of following acids
H2SO4=2
H3PO3=2
H3PO4=3
HNO3=1

As we know N=basicity × M

solving all we get Normality of H3PO4=3 which is maximum .
Therefore solution of 1M H3PO4 will have highest normality
