Title: Diluting vinegar
Post by: Fish200398 on February 25, 2020, 02:53:59 PM

Given : Suppose the concentration of vinegar is to be diluted precisely to 1/10 with the aid of a
volumetric flask and an apparatus A, pipet or buret, which is wet as it has been washed
with distilled water. Whats the name of apparatus A used and the method of using it.

Key answer : pipet, to use after rinsing several times with the vinegar to be diluted

Can anyone tell me what they do in the question? I dont even understand the question..

Also the key answer : rinsing with the vinegar, whats to be diluted?

You would use a pipette (used for transferring substance) rather than a buret (used to measure quantity of substance)
You rinse the pipette to make sure any residual substance is vinegar and not water so that the transferred vinegar isn't diluted.

Why buret cant be used? Buret can measure the vinegar to be diluted 0.1?

Technically you could use a burette, but in this case the pipette is much easier and much more convenient.
