Answer to Question #202505 in General Chemistry for Crimston Himbler

Question

HCl is being titrated with NaOH. I want to find the concentration of HCl. A recently cleaned burette was left wet and then filled with NaOH. How would this affect the concentration of HCl? Would it make it appear as though the concentration of HCl is higher or lower than it actually is and WHY?

Answer 1

During the course of the titration, the titrant (NaOH) is added slowly to the unknown solution.As it is added, the HCl is slowly reacted away. The point at which exactly enough titrant (NaOH) has been added to react with all of the analyte (HCl) is called the equivalence point.
