Unformatted text preview: 2, Glass stirring rods 3. Graduated cylinder (250 ml) 4. Ring stand 5. Spatula 6. Watch glass 7. 2, Flask (250 ml) 8. Buret (0.1 ml precision) 9. 2, Beakers (50ml) Procedures: 1. Mass out 3.15 g of H 2 C 2 O 4 * H 2 O and put it into a flask. 2. Add 250 ml of distilled water to dilute the solution. 3. Mass out 0.99 g of NaOH and put it into another flask. 4. Add 250 ml of distilled water to dilute the solution. 5. Stir the NaOH solution until all the solid compound has dissolved. 6. Prepare a buret by rinsing it with distilled water followed by 10 ml of NaOH solution. 7. Connect the buret to the ring stand. 8. Add 50 ml of the NaOH solution into the buret. 9. Place the flask containing the H 2 C 2 O 4 * H 2 O under the buret. 10. Add two drops of Phenolphthalein to indicate the end point. 11. Constantly swirl the flask as the NaOH drips into the flask. 12. Stop the titration and read the buret when you reach its end point....
