What type of pipette should you use to accurately measure 25 ml of a solution?
What type of pipette should you use to accurately measure 25 ml of a solution?
To measure 25 mL of water you could use a beaker, or an erlenmeyer flask because these estimate to the 1's place digit. This would not be an accurate measurement. For 25.00 mL you want something that estimates to the hundredths place, so you are going to want to use something like a buret or a pipet.
How accurate can a pipette measure?
A pipette is accurate to the degree that the volume delivered is equal to the specified volume. ... A pipette can be consistently inaccurate but this inaccuracy could be very precise, for example if a pipette reads consistently low.
What can be used to measure 25.0 ml accurately?
When you need to measure 25.0 ml of a liquid, the graduated cylinder is a perfect choice. The graduated cylinder has calibrations that measure up to as low as 5 ml. Therefore, 25.0 ml would measure accurately.7 sept 2020
Which pipette is the most accurate?
volumetric pipette
How much does a volumetric pipette hold?
Typical volumes are 1, 2, 5, 10, 20, 25, 50 and 100 mL. Volumetric pipettes are commonly used in analytical chemistry to make laboratory solutions from a base stock as well as to prepare solutions for titration. ASTM standard E969 defines the standard tolerance for volumetric transfer pipettes.
Is there a 5 mL volumetric pipette?
"5mL Volumetric Pipet. ... These pipettes have a large bulb just above a long narrow portion and are calibrated for a single volume.27 oct 2016
What are the types of volumetric pipette?
Four main types of volumetric glassware are common: the graduated cylinder, the volumetric flask, the buret and the pipet. These have specific uses and will be discussed individually.
