1. Standarization of NaOH with Potassium Hydrogenphthalate (KHC8H404) The hygroscopic nature of NaOH requires its solution to be standardized with a stable primary standard such as potassium hydrogen phthalate. The exact molar concentration of NaOH solution can then be accurately determined. 1.1) Prepare the stock NaOH solution by dissolving about 4 g of NaOH pellet in 100 mL of deionized water. Note that NaOH is a hazardous chemical which is corrosive to skin and irritant to eye‚ be cautious and
