Remember that unlike most glassware the.
. Learn how to read a buret correctly. Report the buret reading to one digit beyond the markings on the buret. At the bottom of the tube is a stopcock or valve used to stop and start.
A burette consists of a long graduated tube often glass that is marked with volume measurements. Note in this photograph that although the. You must be at eye level with the bottom of the meniscus curved surface of liquid to read the burette.
Since your buret is graduated to 01 mL you will read your buret to 001 ml. How to read the meniscus. 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.
Remember that the volume starts at zero at the top. Placing a piece of white paper behind the buret can help to determine a clearer reading. Also be sure to include uncertainty in any buret reading.
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. The second decimal place is an estimate but should be recorded.
To read a buret look at the bottom of the meniscus. Read the center of the meniscus or the bottom of the U-shape. Water has a meniscus that curves down.
This video follows the. Before beginning to record a reading examine the buret closely. A parallax error can be caused by reading from above or below the knee.
It is important that you read the buret with the meniscus at eye. Read Buret Tubes When reading a buret it is important that your line of sight be in a direction perpendicular to the buret column. When reading a buret remember to read it against a uniform background and to have the meniscus at eye-level.
The correct reading is 1950 mL. The curved surface of a liquid is called a meniscus. Due to parallax error the reading can be 1962.
On other types of glassware such as the graduated cylinder zero was at the bottom of the scale with values increasing. In order to read better keep a piece of paper in front of your eyes. You fill the buret to the 000.
You read the liquid level.
