Q(2): Which of the following will affect the calculated molarity of phosphoric acid solution when its titrated with standard NaOH to be higher than the correct value? Select one: a. Rinsing the inner wall of the titration flask with distilled water during addition of NaOH b. Rinsing the titration flask with small amount of phosphoric acid c. Rinsing the buret with NaOH before filling it d. Presence of air bubble in the pipette that was used to deliver phosphoric acid Q(3): Which of the following statements is Correct Select one: a. Titrant should react completely with the analyte so that satisfactory end points are realized b. The reaction of the analyte with titrant should be slow to allow the detection of the end point c. Equivalence point and end point have the same physical meaning d. In titration of weak acid it is better to use weak base as titrant
