Problem

A 25.0 mL sample of 0.105 M HCl was titrated with 315 mL of NaOH. What is the concentration of the NaOH?

Solution

We are being asked to find the concentration of the 315mL of NaOH used to titrate 25.0 mL sample of 0.105 M HCl .

  • The problem assumes that the titration is completed or is at the equivalence point. 
  • This means that the moles of the acid and base are the same
  • Now since that we a strong acid and a strong base, we can use the equation below to solve.
