Before a burette is used, it needs to be cleaned. During the cleaning process, usually, water is introduced into the burette. Be the water clean or not, if the burette is then used without rinsing it with the solution that it is going to be filled with, the result of that analytical exercise will not be precise and accurate. The reason is that water residue in the burette would dillute the solution when it's filled in the burette which would make it impossible to determine the exact concentration of the solution moved by the burette. By rinsing and re-rinsing the burette several times with the solution it is going to be filled with, residue water from the cleaning process would be successfully removed from the burette as are other leftover substances from the cleaning process. This practice is quite important as basic analytical technique.
Base burettes are used for base titrants. Basically this is used in titrations where the analyte is an acid.
The burette can be filled with either acid or base. The acid will go into the burette only if you want to titrate a base , i.e. you don't know the concentration of the base and want to find out. The solution of known concentration goes always into the burette (in order to be able to measure the volume taken to complete the reaction) and so if you wanted to find out the concentration of an acid you would put the base into the burette.
The general use of acid/base burettes I am familiar with is to determine the concentration of either the acid or base from the known concentration of the other solution. The two burettes are set side by side, and a quantity of acid is placed into a Erlenmyer flask from the acid filled burette and then the solution from the base filled burette is run into the flask along with indicator to the point of color change. By the amount titrated one can use a simple equality to find the concentration of the unknown solution.
A burette, or buret, is a uniform-bore glass tube with fine gradations and a stopcock at the bottom, used especially in laboratory procedures for accurate fluid dispensing and measurement. The buret is commonly used in titrations to measure precisely how much liquid is used.
Yes, as it will serve to dilute the concentration of the sodium hydroxide being placed in the buret. You will being adding a known concentration of sodium hydroxide and ending up with an unknown concentration.

You would be lead to assume that there was more NaOH in the pipet than there actually was. Since when for example the pipet reads 10ml this is talking when the space in the burette is also filled up. When it is that the reaction takes place between the NaOH and acetic acid you would think that you used more NaOH than you really did, which will ultimately make you think more acetic acid was in the vinegar than was in fact.
Clouds are air masses filled with tiny water droplets or ice crystals.

Any fluid!!! It is like a pipette, however, it is usually more accurate because you can use a burette loader which allows fine tuning of the liquid but not as fine as a gilson pipette. Basically, it is just a piece of apparatus used measuring liquids.
The measure of volume used in the titration will be inaccurate, because there will appear to be more titrate used than has actually been dispensed.
The thing that happens in water droplets to cause rainbows is the light shines through it. rainbow9897654321: it is a prism that make it white is made of all color it reflects for the droplet when i goes through the glass its a rain bow that is filled with water its a experiment but you got to put it in the sun with a glass filled with water
