It takes 58 mL of 0.124 M KOH to neutralize 34.5 mL of H2SO4 solution. What is the concentration of the H2SO4 solution? Answer in unites of moles/liter.

Answer 1

H2SO4 + 2KOH ==> K2SO4 + 2H2O

moles KOH used = M x L = ??
Convert moles KOH to moles H2SO4 using the coefficients in the balanced equation.
MH2SO4 = moles H2SO4/L HS2SO4. Solve for M H2SO4.
