Titration of a strong acid with a strong base. The pH curve for titration of 50.0 mL of a 0.100 M solution of hydrochloric acid with a 0.100 M solution of NaOH (aq). For clarity, water molecules have been omitted from the molecular art.
Required:
What volume of NaOH(aq) would be needed to reach the equivalence point if the concentration of the added base were 0.270 M?
