How is a burette better than a measuring cylinder?

How is a burette better than a measuring cylinder?

The burette is better for delivering a precise amount of volume, it’s best for titrations. A graduated cylinder is good for delivering a large amount of liquid (~1mL to 1L) with only a fair degree of accuracy.

How precise is a burette?

The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined. Compared to a volumetric pipette, a burette has similar precision if used to its full capacity, but as it is usually used to deliver less than its full capacity, a burette is slightly less precise than a pipette.

What is the precision of a 10 mL graduated cylinder?

The general rule of thumb is: you can estimate one more digit past the smallest division on the measuring device. If you look at a 10mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1mL). That means when you read the volume, you can estimate to the hundredths place (0.01mL).

How do you read a 25 mL graduated cylinder?

In the 25-mL graduated cylinder, first subtract 25 mL – 20 mL = 5 mL. Next, count that ten intervals are between the labeled graduations. Therefore, the scale increment is 5 mL/10 graduations = 0.5 mL/graduation.

What is the volume of 25 mL of water?

2 Answers. The volume of 25⋅mL of water is 25⋅mL .

What are the graduations on a 25 mL graduated cylinder?

Which is the most accurate way to read a graduated cylinder?

Reading a Graduated Cylinder Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.

What can be measured with a graduated cylinder or a ruler?

In science, length may be measured with a metric ruler using SI units such as millimeters and centimeters. Scientists measure mass with a balance, such as a triple beam balance or electronic balance. In science, the volume of a liquid might be measured with a graduated cylinder.
