Question

50 mL of a 20 M $HCl$ solution is diluted to 5 L. What is the final normality of $HCl$ solution?

• A. 0.5 N
• B. 1.0 N
• C. 0.2 N
• D. 0.8 N

Answer 1

The correct option is C 0.2 N

As per the concept of dilution,
$M_1{V}_1=M_2{V}_2\Rightarrow (20\times 50)=(M\times 5000)$
On solving, M = 0.2 M
n-factor for $HCl$ = 1.
So, normality = molarity
Concentration after dilution = 0.2 N
