Question

rank the following items in order of accuracy when they are used for their intended purpose: volumetric pipet, beaker,erlenmeyer flask,mohr pipet,graduated cylinder,volumetric flask,buret


my answer
MOHR PIPETTE 1
VOLUMETRIC PIPETTE 2
BURET 3
VOLUMETRIC FLASK 4
GRAD CYLINDER 5
BEAKER 6
ERLENMEYER FLASK 7

Answer 1

I have spent a lot of time looking for a site to which I could refer you to for this question but to no avail. So here is my best educated guess and the reasoning.
I think volumetric pipets are #1 in accuracy. They require only one measurement reading (when the pipet is full).
buret I rank as 2. Basically I think the mohr pipet and buret are about the same but the stopcock on the buret is easier to control than the finger on the mohr pipet so I rank the buret higher.
volumetric flask as 4 as you have it
graduated cylinder as 5 as you have it.
I would put the Erlenmeyer flask as 6 and over the beaker because of the shape of the Erlenmeyer flask. Since the sides slope markings at the top of the flask are easier to read than they are on the beaker so I think the Erlenmeyer flask can be read more accurately.
