Question

Based from the given problem, What is the Normality of the sodium hydroxide solution?

Part 1: Alkalimetry Preparation and Standardization of 1N Sodium Hydroxide A. Preparation Dissolve 14.7 grams of sodium hydroxide pellets in 100 ml of carbon-dioxide free water. Cool the solution to room temperature Add a freshly prepared saturated solution of barium hydroxide until no more precipitate forms. Shake and filter. Transfer it in a 250 ml volumetric flask, then add sufficient quantity of carbon dioxide free water to make 250 ml. B. Standardization Weigh accurately about 5 grams of potassium biphthalate, previously crushed lightly and dried at 120 degrees Celsius for 2 hours and dissolve it in 75 ml of carbon dioxide free water. Add 2 drops of phenolphthalein TS. Transfer 50 ml of the sodium hydroxide solution in a Buret and titrate the potassium biphthalate solution with the sodium hydroxide solution until it produces a permanent pink color. Note: 24 ml NaOH solution was used to change the color from colorless to pink color *Titer Value: Each ml of 1 N NaOH is equivalent to 204 mg of Potassium biphthalate Table: Data Wt of KHP (g) MW of KHP meg of KHP Volume of sodium hydroxide solution used (ml) Normality Trial 1 5.000 g 24.000
