Problem

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

 

Solution

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:

Reactants:

2SO4

▪ oxyacid → 2 more oxygens than hydrogens → strong oxyacid
▪ a strong acid → will completely dissociate in solution
H2SO4(aq) → 2 H+(aq) + SO42-(aq) 

NaOH
