Pipette is used to transfer the solution, so it is important that it delivers known volume. Wrong forum!

From what I learnt, the error can be +0.05 or -0.05, so the total error is 0.05+0.05 Reply RevisionNad Follow 15 followers 3 badges Offline 3 ReputationRep: Follow 10 18-12-2014 19:50 There was this question in my mock...

However, their accuracy is usually much lower than the accuracy of volumetric glass described above. If paper is hold half an inch behind a burette with a stripe about a half an inch below meniscus, solution surface seems to be black and is much easier to Page was last modified on June 17 2009, 12:07:29. http://back2cloud.com/percentage-error/percentage-error-of-a-10ml-syringe.php Reply Method Follow 3 followers 2 badges Offline 2 ReputationRep: Follow 2 14-03-2007 19:36 (Original post by Couldxbe) Can anyone tell me the error involved in: 1) 100cm3 gas syringe 2)

For a buret the reading error is about 0.02 mL and you read twice (once at the beginning and once at the end) so that is a combined reading error f Uncertainty Of Measuring Cylinder Depending on the glass class difference between nominal and real volume can be neglected or have to be taken into account when calculating titration result.

If you titrate with 10 mL that reading error is (0.04/10)*100 = 0.4% or 4 parts/thousand (ppt) But out of a 50 mL titration that is just 0.8 ppt (0.08%) You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM.

On the contrary, volumetric flask is known to contain required volume, but if you will pour the solution to some other flask you will never know how much of the solution As it often happens, this is not a rule to be followed blindly - in the case of small samples large volumes mean dilution, which in turn may mean problems with news This is an important distinction - when you empty pipette you deliver exactly required volume and you dont have to worry about the solution that is left on the pipette walls

Meniscus surface is in fact a little bit below the 1.4mL mark, so you may read it as 1.42mL, assuming it is about 1/5 of the scale distance.

And of a 100 mL pipet is (0.25/100)*100 = 0.25% The lesson out of this is to use larger volumes to reduce volumetric errors. It can be interesting to check relative accuracies of volumetric glass calculated wih the use of the tolerances data.
