We have continued to emphasize reduced-scale experimentation (e.g., titrations involving 1- m L burets ), but we have also expanded and added detail for experimental procedures for those who prefer to use macroscale experimentation using 25 - or 50- m L burets . In general, we see ... To avoid parallax error (a misreading caused by an improper location of the observer's eye level), your eye should always be level with the meniscus when you are making a reading. The volume is ...

Can anyone please tell me which one of the following is the most accurate method of Volume measurement for 6 m L of water (density= 1g/ m L ): Graduated Cylinder, Pipet, or Buret . Also, how can you explain your answer. Every help would be ... Hi, I think I can distinguish between the terms "to contain" and "to deliver" :) The graduated cylinder graduated in 1.0 m L increments ( error : +/- 0.5 m L ), and both buret and pipette are graduated in 0.1 m L ( error : +/- 0.05 m L ).

A buret is used to deliver solution in precisely-measured, variable volumes. Burets are used primarily for titration, to deliver one reactant until the precise end point of the reaction is reached. Filling Buret. To fill a buret, close the stopcock at the bottom and use a funnel. You may need to lift up ... This works better than a funnel for the small, 10 m L burets . Be sure the transfer ... solution is flowing. If an air bubble is present during a titration, volume readings may be in error .
