Why a base is taken in pipette?
The purpose is to extract a known volume of solution.
Why is it important to calibrate a pipette prior to it being used to make up standard solution?
Pipettes are used to move specific volumes of fluid between containers. For very small volumes, or very precise applications, a large error in the desired fluid volume can have a very large impact. Calibrating a pipette ensures that the volume desired is the volume collected. Proper sealing of pipette tips can also have a large impact on fluid volumes collected.
What do you call the instrument that holds the pipette?
The instrument that holds the pipette is called a pipette bulb or a pipette filler. It is used to create suction for drawing liquid into the pipette and controlling its release.
What is another name for Pasteur pipette?
Another name for Pasteur pipette is transfer pipette.
What are the properties of slime?
The physical properties of slime include:- Borax Solution- Food Dye- PVA Glue- Eye Dropper/ Pasteur Pipette
How is a pipette prepared?
1. Clean the pipette with a solution of an adequate reactive. 2. Wash with tap water. 3. Wash with demineralized water. 4. Dry the pipette.
What is the procedure when the solution has drained from the pipette and the meniscus has reached the tip of the pipette?
If the solution has drained from the pipette and the meniscus has reached the tip, it means you have overdispensed. To correct this, wipe the tip of the pipette with a clean tissue and carefully touch the tip against the inside wall of the vessel to remove excess liquid. This will help adjust the volume to the desired level.
What are the uses of measuring pipette?
it is used to measure specific ammounts of solution
Why a base is taken in pipette?
The purpose is to extract a known volume of solution.
Why should you not blow out the small amount of solution that remains in a pipette when measuring liquid?
The calibration of a pipette is made taking into account this small volume.
Why should you not blow out the small amount of solution that remains in pipette when measuring liquids?
The calibration of a pipette is made taking into account this small volume.
The pipette is not rinsed with the potassium hydrogenphthalate solution?
Failure to rinse the pipette with the potassium hydrogenphthalate solution can result in inaccurate measurements. Rinsing ensures that any residue from previous solutions is eliminated, preventing contamination and improving the accuracy of the current measurement. It is important to follow proper protocol to maintain the precision and reliability of the experimental results.

What is a pipette bulb use for in chemistry?
A pipette bulb allow a liquid to be sucked up into the pipette, so avoiding having to use your mouth to suck the liquid up. Apart from avoiding often toxic liquids getting into your mouth, it also avoids contamination of the liquid.
What is a device for actually measuring very small amounts of liquid?
pipette
What are the best practices for using a TD pipette in a laboratory setting?
When using a TD pipette in a laboratory setting, it is important to follow these best practices: Calibrate the pipette regularly to ensure accurate measurements. Use the appropriate tip size for the volume being measured. Hold the pipette vertically while aspirating and dispensing liquids. Avoid touching the tip to any surface to prevent contamination. Release the plunger slowly and steadily to dispense the liquid accurately. Rinse the pipette with the appropriate cleaning solution after each use. Store the pipette in a designated area to prevent damage or contamination.
Is it advantageous or disadvantageous to use one pipette throughout the dilution process and why?
It important to use the same pipet throughout the experiment because so as the solution will not be contaminated or changed during the reaction
