(0.05/50mL x 100 = 0.1)...ok thats the begining...but i have also found somewhere that... "when you use a burette you take a reading at the start and the end , so you have two errors of 0.05 cm3 i.e. total error = 0.10 cm3. If you are using your burette to do a titration there may be another error of one or two drops which is due to your judgement of when the indicator changes colour. This means that in a titration (as opposed to just using a burette to measure a volume) you may have an error of 0.2 cm3." so...(0.2/watever measurement x100)...BUT..in my past courseworks..i divided (0.05/ measurement x 100)..and i R

Shall i just make it up? Will I lose Marks if i dont have any % errors? #1 Tamxxx, Apr 22, 2007 hash118118 New Member Joined: Feb 21, 2007 Messages: 237 Likes Received: 0 Tamxxx said: ↑ Im in my evaluating part, and i have to include % errors, the thing is I only have one % error in my titration experiment and my teacher said that you have to include percentage errors for all measurements, The thing is how can if i didnt have any errors?:confused: Shall i just make it up?

I don't think you understand the concept of percentage errors - you are analysing the errors assosciated with the appartu

Quantitative Analysis by R.A. Day, A.L. Underwood Complete list of books Titration » Burette, pipette, flask - volumetric glassware During titration experiments you will be using several types of volumetric glass. They all are designed to help measure volume of a liquid. Some percentage error types of the volumetric glass can be used only to measure predefined volume of solution. These are volumetric flasks and single volume pipettes. They are characterised by a a high accuracy and repeatability of measurements. Flasks are designed to contain (TC, sometimes marked as IN) known volume of the solution, while pipettes are generally designed percentage error of to deliver (TD, sometimes marked as EX) known volume (although in some rare cases they can be designed to contain). 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 and in pipette tip. At the same time you will never know how much solution was in the pipette. 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 was transferred. Both kinds of glass were designed this way as they serve different purposes. Volumetric flask is used to dilute original sample to known volume, so it is paramount that it contains exact volume. Pipette is used to transfer the solution, so it is important that it delivers known volume. Note, that volumetric pipettes are designed in such a way t
