This means that although you can add the NaOH rapidly at first at
Read Buret Tubes. When reading a buret it is important that your line of sight be in a direction perpendicular to the buret column. Note in this photograph that although the bottom of the meniscus is clearly outlined the variability of the background does not always offer such visibility.
You read the liquid level using the bottom of the meniscus. The meniscus is created by surface tension of the liquid and the extent thatthe liquid "wets" the wall. Part of the structure of the meniscus involves reflection of light. What must you do to a Buret before using it A buret
2019-10-2 · When you read a scale on the side of a container with a meniscus such as a graduated cylinder or volumetric flask it s important that the measurement accounts for the meniscus. Measure so that the line you are reading is even with the center of the meniscus. For water and most liquids this is the bottom of the meniscus.
2014-1-20 · How to Record Buret Readings (p.95) 1. The curved surface of a liquid is called a meniscus. Water has a meniscus that curves down. It is important that you read the buret with the meniscus at eye level to avoid the problems of parallax. You know you are not at eye level if the marking on the buret on the backside is visible as in Fig.11.1.
Reading the Buret Get your eye level with the bottom of the meniscus. Looking up or down on the meniscus will cause a parallax error. Read the buret to the nearest 0.01 mL. The marks occur every 0.1 mL so the last number will have to be an estimate.
Read the center of the meniscus or the bottom of the U-shape. Figure How to read the meniscus. The correct reading is 19.50 mL. Due to parallax error the reading can be 19.62 mL or 19.42 mL. The first and final reading of the burette should be recorded.
2019-7-12 · The buret is etched with calibration markings at 0.10-mL intervals allowing the estimation of variable liquid levels to the hundredths of a milliliter (0.00 mL). The meniscus must be viewed horizontally with the reading taken from the bottom of the meniscus. Note on waiting time

2020-3-19 · Your eye must be on the same level as the bottom of the meniscus to read the volume correctly. The meniscus formed by a non-wetting liquid such as mercury (Hg) is convex with the highest point in the center. In the case of a convex meniscus the highest point is used to make the reading.
2008-1-29 · 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 are 24.2 mL.

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.
2019-6-6 · Sad tale of a meniscus misread. Few people take the time to consider the importance of water menisci in their lives. But imagine this chilling scenario In your high-school chemistry final exam you mistakenly read a meniscus as 72 milliliters (ml) instead of the correct 66 ml (in this picture) and thus you get an 89 on the test instead of a 90.
