In reading numbers from a graduated scale you always interpolate between the graduation marks.

Therefore the top-most graduation of the buret is. Read Buret Tubes. Read the center of the meniscus or the bottom of the U-shape.

The curved surface of a liquid is called a meniscus. Zero is close to where you fill your N a O H solution in the largest value is close to the valve. If the bottom of the u is between the marks for 03 and 04 you record it as 04mL.

Before use a buret should be cleaned and pre-rinsed with the solution to be delivered. 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 correct reading is 1950 mL.
