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 sodium hydroxide together with the accuracy (as represented by the 95% confidence limit).

Please explain the purpose of standardization. After standardization, a titration was performed with the above titrant and the analyte was KHP with unknown concentration. Please explain why it was important to standardize before performing the next titration.
