Preparation of Sodium Hydroxide Titrant: Prepare 500 mL of a 0.1 M sodium hydroxide solution by dilution of a 1 M sodium hydroxide stock reagent or from solid NaOH. This dilution need only be performed to 5% accuracy, that is, using a graduated cylinder and an Erlenmeyer flask. Store the diluted solution in a polyethylene bottle. Standardize the diluted solution against dry, solid KHP (potassium hydrogen phthalate) using phenolphthalein as an indicator and label the bottle with the concentration of...
