Question

100 ml of 0.1 M H2So4 with 50 ml of 0.1 M of NaOH find normality​

Answer 1

Answer:Molarity of the resulting solution=M1V1+M2V2/V1+V2

                                      0.1*100+0.1*50/150 ...................               ( 100 ml+50 ml)

                    M resulting=15/150=0.1 M

Normality=Molarity*Valency

hence, in H2So4-valency=2;  N1=0.1*2=0.2 N

       Valency of Naoh=1 ; N2=0.1*1=0.1 N

 N resulting=N1V1+N2V2/V1+V2

               =0.2*100+0.1*50/150

                =25/150   =1/6  =0.16 N.
