Question

If 100 ml of 0.1N HCl and 200ml and 0.2N NaOH, react
with each other, then resultant solution normality is
0.1N
0.2N
0.01N
0.02N​

Answer 1

Yo

this is an acid base reaction and it's normality can be found by using

N1V1-N2V2=N(V1+V2)

200*0.2-100*0.1=N*300

N=0.1

Hence option 1 is correct

Hope this helps
