Would adding extra deionized water to the Erlenmeyer flask during the titration affect the molarity of the NaOH solution? Explain your reasoning. 2. Why is it important that air bubbles from the buret or valve are removed prior to starting the titration? 3. Why is it proper to read the initial volume of the buret instead of trying to adjust the volume to a round number such as 0 mL? 4. Calculate the molarity of a NaOH solution if 23.25 mL of NaOH is titrated with 0.475 grams of KHP and 1.25 ml of 0.100 M HCl is required
