Question

During the observation of burette reading,eye level and solution level in the burette must be in

Answer 1

Answer:

• There are two levels of reading in the burette, if the solution in the burette is colored then the reading must be taken in the upper meniscus and the solution in the burette is not colored and then the reading must be taken in lower meniscus.
• The eye should straight away point towards the bottom reading of the solution thereby if not it can result in the parallax error.
• To avoid these check for the accurate burette efficiency henceforth.
