How to Read a Buret
If the bottom of the u is between the marks for 03 and 04 you record it as 04mL. Zero is close to where you fill your ceNaOH solution in the largest value is close to the valve.

Remember that the volume starts.
. Read Buret Tubes When reading a buret it is important that your line of sight be in a direction perpendicular to the buret column. The correct reading is 1950 mL. Read the buret volume at the bottom of the meniscus.
In this chemistry tutorial video we describe the correct way one would read the volume off a burette using the graduation lines that appear on a burette. When reading a buret remember to read it against a uniform background and to have the meniscus at eye-level. Graduated marks on the buret indicate the amount of liquid that has been drained.
The first and final reading of the burette should be recorded. If you are at eye level the markings should be as shown in Fig. Before beginning to record a reading examine the buret closely.
A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid especially of one of the reagents in a titration. To read a burette accurately you take the very bottom of the u as the level of the fluid. Therefore the top-most graduation of the buret is.
The scale on a burette typically is ascending from top to bottom. When reading a measurement on a burette it is important to lower yourself so your eyes are even with the fluid level. You must be at eye level with the bottom of the meniscus curved surface of liquid to read the burette.
Due to parallax error the reading can be 1962 mL or 1942 mL. Report the buret reading to one digit beyond the markings on the buret. The fluid in a burette will appear curved called the.
Note in this photograph that although. Read the buret volume at the bottom of the meniscus. A parallax error can be caused by reading from above or below the knee.
The scale on the buret goes from zero at the top to 5000 mL at the bottom. A buret is designed to deliver a certain volume of water. READING the BURET Remember the numbers start at 000 on top and go to 2500 on the bottom The curved surface at the top of the liquid level is called ameniscus.
It is easy to forget and. On other types of glassware such as the graduated cylinder zero was at the bottom of the scale with values increasing.
