Question
If A buret was not held vertically when a measurement was taken, but slanted to the side a small bit while the measurements were taken.
The student using the buret read an initial volume, then a final volume, and took the difference between the two volumes to calculate the volume of liquid delivered.
How would the accuracy of the volume of liquid delivered by the slanted buret be affected? (Would the accuracy be better, as good, or worse than a buret that was held vertical?) Why or why not?
Also how the precision would be and why?
Explanation / Answer
When reading a buret it is important that our line of sight be in a direction perpendicular to the buret column.
Another problemis poor drainage. A bubble in the nozzle of a buret wikl cause an inaccurate volume reading
