Question

Equal volume of 1M hcl and 1M H2SO4

Answer 1

Depends. If you titrated to the first equivalence point, they used the same amount. However, if you titrate until all acid has be titrated, then the H2SO4 solution and it will use twice as much. The equations below should clarify.

HCl

HCl + NaOH → NaCl + H2O

H2SO4

H2SO4 + NaOH → NaHSO4 + H2O

NaHSO4 + NaOH → Na2SO4 + H2O
