We’re being asked to find the concentration of NaOH that is titrated with 45.5 mL 0.100 M H2SO4.
Let’s first write the balanced reaction between H2SO4 and NaOH:
▪ oxyacid → 2 more oxygens than hydrogens → strong oxyacid
▪ a strong acid → will completely dissociate in solution
▪ H2SO4(aq) → 2 H+(aq) + SO42-(aq)
A 25.00 mL sample of NaOH is titrated with 45.5 mL of 0.100 M H2SO4(aq). What is the concentration of the NaOH solution?
a. 0.091 M
b. 0.182 M
c. 0.364 M
d. 0.455 M
e. 0.728 M
