A pipet delievers 9.98g of water at 20 degrees celsius What volume does the pipet deliver?
10.0cm^3
What is a device for accurately measuring very small amounts of liquids?
Certain micropipettes can accurately deliver fluids as small as 1 microliter (or 1 millionth of a liter).
What happen if dirty pipet is used and droplets of liquid adhered to inner wall of pipet?
Any serious determination of a physical property is made on very pure compounds; any impuridty modify the results.
Remove the drop suspended from a pipet tip by.?
by touching it to the wall of the waste beaker
In determining the density of a liquid a student left air bubbles trapped in the volumetric pipet Did this give a density less than expected or greater than expected why?
Well the air bubbles contrain a element called SW (short for swag). When swag is produced during a density excitement, the results vary. Usually results favor swag. To get around this trouble, you must not produce swag! To do this, dress like a hill billy, get rid of your friends, and make sure to tell everyone you meet to "f*** off". Once swag is not produced in the density experiment, you will receive the true density results! Pure Density.
Why do you never pipet by mouth in the chemistry lab?
Pipetting by mouth risks ingesting the chemical you are trying to suck into the pipet. Even if the solution is harmless, you can't be sure that the pipet itself is clean. Who knows what chemical was in it last? Instead, use a pipet bulb or syringe to draw up the solution. These are generally available in any laboratory where you might need to use a pipet.
Why is it important to use the same pipet throughout a titration experiment?
so the solution will not be contaminated or changed during the reaction
Suppose that after delivery several drops of the water cling to the inner wall of the pipet because the pipet wall is dirty How does this technique error affect the reported density of the solid?
If water droplets stick to the inside of the pipet it will cause the volume of the water to be a lower value then what the pipet is calibrated to therefore the density of the water will be higher. It will affect it, because the mass that you are weighting will be greater than it should be, and this will give you a greater density.
What is Saint-Baudille-et-Pipet's population?
Saint-Baudille-et-Pipet's population is 232.
What is the pipet use for?
In one type of experiment, a pipet is used to distribute DNA information. The process is used in Gel Electrophoresis. With the pipet you syphon the DNA material and the chemicals used to bring out the genetic information and you squirt it into the notches in the gel. That is how a pipet is used in one instance.
A pipet delievers 9.98g of water at 20 degrees celsius What volume does the pipet deliver?
10.0cm^3
What is the area of Saint-Baudille-et-Pipet?
The area of Saint-Baudille-et-Pipet is 36 square kilometers.
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
Why do you take acid in buret?
because ,we don't suck the acid ,pipet used for sucking ,so we take base in pipet and take acid in buret.
How do you deliver 5.00 mL of liquid by using a transfer pipet?
Absorb 5 mL of liquid in the pipet and then put it in your test tube, bottle, etc.
What are the two major types of pipet?
To contain and To deliver
How do you calibrate a pipet?
A pipet is calibrated by pouring a liquid of known volume into it and taking the reading in order to determine by how much it might be deviating. This technique is regarded as a quantitative method.
