If you titrated 50 mL of HCl and 50 mL H2SO4, each of the same molarity, with NaOH. What is the numerical ratio of the volume of NaOH required for HCl compared to that for H2SO4?

Answer 1

I assume you want to titrate BOTH H ions of the H2SO4. Let's just make the problem easier by assuming 0.1M HCl, 0.1M H2SO4, and 0.1M NaOH.
mmols HCl = 50 x 0.1 = 5
mmols H2SO4 = 50 x 0.1 to titrate the first H and another 5 to titrate the second so 10 mmols for H2SO4.

Now if you titrate the HCl with 0.1M NaOH it will take 50 mL and if you titrate the H2SO4 with 0.1M NaOH, it takes 50 mL for the first H and another 50 for the second so 100 mL for the H2SO4. So the ratio of VHCl.VH2SO4is .....
