Question

300 ml of 4 M HCl and 200 ml of 0.5 M NaOH are mixed with each other. Normality of the resultant mixture is ----- N

Moderate

A

2.4
B

2.8
C

2.6
D

2.2

Solution

$V_{a} N_{a} = 300 (4) 1; V_{b} N_{b} = 200 (0.5) 1; V_{a} N_{a} > V_{b} N_{b}; N = {[H]}^{+} = \frac{V_{a} N_{a} - V_{b} N_{b}}{Total volume of the mixture}; N = {[H]}^{+} = \frac{1200 - 100}{500} N = 2.2 N;$
