Approximately how many milliliters of
the HCl or NaOH will be required?
Describe how you would prepare exactly 100 mL of 0.150 M picolinate buffer, pH 5.69. Possible starting materials are pure picolinic acid (pyridine-2-carboxylic acid, FM 123.10), 10 M HCl, and 1.0 M NaOH. Place the given steps in order. Not all of the steps will be used. First step Weigh out the required mass of picolinic acid. Dissolve the picolinic acid in -75 mL of water in a beaker. a Add NaOH until the measured pH is 5.69. Transfer the solution to a 100 mL volumetric flask. Use small portions of water to rinse the contents of the beaker into the flask. Dilute to 100 mL and mix well. Last step Answer Bank Add HCl until the measured pH is 5.69. Approximately how many milliliters of the HCl or NaOH will be required? volume: ml.
