Answer 1
This is a result of Dalton's Law of Partial Pressures. Since the water levels were kept equal with the leveling bulb, the total pressure inside the buret is the same as the pressure outside the buret. Thus the total pressure is simply the atmospheric pressure.
Thank you

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
