Drye quantity of primary standard potassim hydrogen phthalate (CHP) for about 2 heat 110°C (Fig. 35-9), and cool in a desiccator. Weigh individual 0,7 to 0.8 g somples (to the nearest 0.Img) into 250 mi conical flasks, and dissolve each in 50 to 75 mL of distilled water. Add 2 drops of phenolphthalein; titrate with base until the pink colour of the indicator persists for 30 seconds (Note). Calculate the concentration of the NaOH solution.
