     · 1 Answer1. The scale on a burette typically is ascending from top to bottom. With other words zero is close to where you fill your N a O H solution in, the largest value is close to the valve. The total amount added (to your vinegar) is the difference between the final and the initial reading. But if your burette was initially filled up to the

  • Volume DeterminationChemistry LibreTexts

     · When using a buret always read the volume to the nearest 0.01 mL. A typical initial buret reading might be 0.73 mL. After the initial reading has been recorded in your notebook, place the titration flask beneath the tip and proceed with the titration as described in the section below entitled Titration.

  • Reading the Volume from a BuretSan Diego Miramar College

     · The first digits are 24, since the last labeled (major) graduation above the meniscus is 24 (remember that the buret has values increasing going down the scale). Next, use the scale increment. There are two unlabeled (minor) graduations above the meniscus (and seven below), and each graduation represents 0.1 mL, so the certain digits of the reading

  • Determining the Volume Delivered

     · The volume delivered by a buret is determined by calculating the difference between the intial volume and the final volume in the buret. Read the initial volume from the buret.

To avoid the problem of parallax, buret readings should be made consistently along a line perpendicular to the buret, as shown in (c) and (d). Directions for Using a Buret

  • How to Read a BuretteMineral Processing & Metallurgy

     · To help you read a burette, first obtain a 3″x5″ card and with a black felt tip pen make a horizontal mark on your card, one inch thick and practically the length of the card. When the top of the black band is held just below the bottom of the meniscus you will see a reflection of the band in the meniscus against the white of the card behind.

  • Calibration of a BuretDepartment of Chemistry

    Calculate the correction value for each volume. If any of your readings exceed a 10 mL increment by a few hundredths of a mL, there is salvation. For example, if for the 10 mL reading your meniscus was at 10.02 mL, you should "correct" the correction value before plotting it by subtracting 0.02 mL from your calculated correction and then plot

  • When reading a buret, where is the initial and

     · When reading a buret, the initial reading should be taken from the top of the glassware and the final volume should still taken at the top. If the buret is completely, the initial volume for most buret would be zero. though, there are some where their initial starts at 50 decreasing to zero.
