FREE Expert 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
