Question

1. What is the definition of an ‘equivalence point’ in an acid/base titration? (1 point)

2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the specific types of glassware you will use.

3. If 15.0 mL of 0.125 M phosphoric acid is titrated with 0.100 M NaOH, what volume of the titrant (in mL) must be added to completely neutralize the acid? Show all of your work (including the chemical equation).

Answer 1

1)Equivalence point of acid-base titration : The point when all analyte acid or may be base will be neutralized by the titrant acid or base. It is determined by the burette reading and expressed in mL or drop of titrant poured.
