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 Percentage Error Of Equipment Flasks are designed to contain (TC, sometimes marked as IN) known volume of the solution, while pipettes are generally designed to deliver (TD, sometimes marked as EX) known volume (although in

Some types of the volumetric glass can be used only to measure predefined volume of solution. B to the right means B class, calibrated to contain (In) at 20°C. Burette is used to add titrant to the titrated solution and it has a scale on the side, so that you can precisely measure volume of the added solution. The examples below all have four significant figures: 0.06027 3.783 2.130 0.004083 6.035 x 105 Now check out the number of significant figures in the answers for each of the following:

Please try the request again. That means that 50mL burettes have the highest resolution. 0.050mL out of 50mL is 0.1%, and that's about maximum precision that we can get from volume measurement when using burette. 100 Ml Volumetric Flask Error And while you may assume the accuracy of the 250 mL volumetric flask and the 25 mL volumetric flask would be the same, often the value will be stamped on the Uncertainty Of Measuring Cylinder Re: Percentage Error Of A Volumetric Flask? « Reply #7 on: May 10, 2006, 12:53:17 AM » There is some standard.
