Question

Calculate the molarities of solutions obtained on mixing50 mL of 0.1 N H2SO4 with 100 mL of 0.1 N NaOH​

Answer 1

Answer:

Answer

Open in answr app

(a) Meq. of H2SO4=100×0.1=10

     Meq. of NaOH=50×0.25=12.5

H2SO4 and NaOH neutralize each other.

Meq. of NaOH left =12.5−10=2.5

Volume of new solution =100+50=150mL

∴NNaOH left =2.5/150=0.0167
