so the solution will not be contaminated or changed during the reaction

When using a pipet can you state the volume of the aliquot without calculating it?
Yes, cause an aliquot is a small volume of something and I believe in this experiment you are also using a volumetric pipet, which should give you the exact volume of the aliquot.
Why do you use burette to measure liquid during titration?
Any (variable) amount of liquid can be measured by weight (mass balance) or by volume.A titration is mostly carried out as volumetric analysis method.An INVariable amount is measured by a (volumetric, standardized) pipet and for Variable volumes a calibrated buret is used to reach high precision standards of AAAC.
Why is it important t o change the pipet tip after each sample has been placed into a well?
it's not
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.
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.
Why it is important to use the same pipet throughout the titration?
To maintain the same errors and to avoid contaminaton.
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
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.

Yes, cause an aliquot is a small volume of something and I believe in this experiment you are also using a volumetric pipet, which should give you the exact volume of the aliquot.
How do you clean your pipet?
Fill a mug or a container with warm tap water. You are using warm tap water because, tap water contains microorganisms which will help flush out the chemicals and it is warm ,because warm water can cleanly stabilize your pipet so it is ready for it's next use. Pinch your pipet inside the water so it fills up to about 15-20 milliliters. Squirt in in the sink. Do the same thing for a few times. Atleast 5 times. Now your pipet is clean and ready for its next use.Why is it important to clean your pipet? It can contain chemicals from your previous experiment which will give inaccurate or wrong results and data.

What is Saint-Baudille-et-Pipet's population?
Saint-Baudille-et-Pipet's population is 232.
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.
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.
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.
