`2N HCI` solution will have the same molar concentration as a

Options

A. `4.0N H_(2)SO_(4)`
B. `0.5 N H_(2)SO_(4)`
C. `1N H_(2)SO_(4)`
D. `2N H_(2)SO_(4)`

Answer

A

Explanation

From the relation
`("Normality")/("Molarity")=("Molecular mass")/("Equivalent mass")=n`
For 2 N HCl
Molarity `=("Normality" xx "Equivalent weight")/("Molecular weight")`
Molarity `=(2xx36.5)/(36.5)=2`
For 4 N `H_(2)SO_(4)`
Molarity `=("Normality" xx "Equivalent weight")/("Molecular weight")`
Molarity `=(4xx49)/(98)=2`
Hence 4 N `H_(2)SO_(4)` and 2 N HCl solution will have same molar concentration.
