Aim: To titrate Sodium Hydroxide with Potassium Hydrogen Phthalate . To also determine the concentration of NaOH in the KHP solution. Hypothesis: When KHP is added to the solution of NaOH and the indicator, the solution will turn clear and neutralize. The concentration of NaOH is going to be very low because it is diluted. Materials required: pipette filler, volumetric flasks(2-4), beakers(2),small white piece of paper, indicator( 2 drops), conical flask, clamp, soap, eye protection, burette, distilled water, cleaning utensils, stand, funnel, solutions( NaOH and KHP) Procedure:
1. Gathered all materials required
2. Wore proper safety equipment
3. All the equipment was washed and gathered.
4. The base (NaOH) and the acid (KHP) were labeled and put into conical flasks and beakers. 5. A rod was screwed into the hole which is in the desk. Also a clamp was placed on the rod. 7. The burette was placed on the clamp.
8. The funnel was rinsed with some acid (KHP) from the inside as well as the outside. 9. A very little amount of acid was poured into the burette to clean it and a beaker was placed underneath the burette. 10. The burette was opened from the bottom to let the acid fall out. 11. A funnel was placed on top of the burette, and a piece of paper was placed between the funnel and flask to let oxygen escape. 12. The acid was poured into the burette until it reached 2 or 3 mL. 13. The pipette was taken to the sink and was rinsed from the outside bottom of the pipette with NaOH. 14. A very little amount of NaOH was poured into the pipette and was disposed into the sink. 15. The pipette was put into the pipette filler and the roller at the side of the pipette filler was rolled up slowly so that the pipette got filled with NaOH 16. The pipette filler was taken off and a thumb was placed on top of the pipette so that NaOH didn’t fall from pipette. 17. The base from the pipette was emptied into the conical flask. 18. A small...
