III. Questions.
1.During the titration several milliliters of deionized water are added to the Erlenmeyer flask containing the KHP solution. How will this affect the calculated concentration of NaOH (too high, too low, or unchanged?) Explain clearly.
2.A 25.00 mL volumetric pipet is rinsed with deionized water. Several drops of water remain in the pipet. It is then used to deliver a 25.00 mL aliquot of the KHP solution into the Erlenmeyer flask in which the sample will be titrated. How will this affect the calculated concentration of NaOH (too high, too low, or unchanged?) Explain clearly.
3.A buret is cleaned and rinsed with deionized water. Some water remains in the buret. It is then filled with the NaOH solution which is being standardized. How will this affect the calculated concentration of NaOH (too high, too low or unchanged?) Explain clearly.
4.During the preparation of the KHP solution, some KHP is spilled on the counter. How will this affect the calculated concentration of NaOH (too high, too low, or unchanged?) Explain clearly.
