Error In Titration Experiment
a titration? experiment and, for each, explain whether the error would result in a calculated molarity that is too high or too low.

The addition of too much acid/base. This will increase the volume or ml you added, which will decrease the molarity. Too low. That is why you want it a very "light" color, not a dark rich one. 2. What you are using to titrate it not pure. For example, If you are supposed to be using 1 M of NaOH to titrate vinegar, and the NaOH has something like a small amount of HCl in it because last lab you forgot to clean the beaker you were holding it in (which perviously had some HCl). This would mean that the molarity is much smaller, because there are other impurities in the same amount of solution. This results in a too low calculated molarity. Your standard solution needs to be accurate! 3. The last error is of course, human error. If you incorrectly find the amount of ml you added to the solution you were titrating, this would mean when you divide the multiply the mols of the solution by the ml, you could have too high amount of moles if you measured too many ml, or too low number of mols if you measured too few ml. This could go either way for mo

Students who conduct a titration experiment may believe their results are as accurate as possible, but like any experiment, titration experiments contain limitations. The goal of a titration experiment is to figure out the measurement of a specific quality in an unknown solution. This can be done by gradually adding small amounts of a known solution (called a titrate) to the unknown solution (called an analyte) until a chemical reaction occurs (called the end point). The most common example of a titration experiment involves slowly adding an acidic solution to an alkaline solution until the pH is completely neutralized. Determining End Point

Apr 7, 2005 #1 dagg3r hi guys assistance in this area would be great just see what i have written and comment on them please thanks! all. im thinking about the errors in titration from doing a typical acid-base titration to talk about in my experiment and these are the errors i came up with. First of all my class got a higher average titre required to error in titrate NaOH against citric acid so im thinking why my titre + concentration of citric acid is low. These are what i came up with. My experimental procedures were given 50ml of lemon juice, get 20ml into conical flask, dilute to 200ml with water, add ethanol near the end to get rid of bubbles, invert the solution 40 times. get 20ml aliquots from the dilute solution, titrate against NaOh and error in titration observe the end point turning to pink from the indicator. * citric acid liquid was lost to splashing before the end point was reached. * buret may have been contaminated with some other solution other than the one being tested. * reading of the buret may have been off. * distilled water remained in the buret before analysis * maybe did not get exact 20ml from the 50ml original My friends told me these notes below but i dont know what they mean someone care to explain: * bubble appeared during titration in the tip of the buret. " the buret contained NaOH so what bubbles are they talking about???/ what error is that?" * Titration nozzle was not flush with the mouth titration tube." no idea what they are talking here heh" So can some one read the experimental procedures and determine some errors / add to my existing one/ tell me if my errors are wrong :p and btw what does the inverting do????? and also how does it change ur results????? and lucky last question does adding too much ethanol do anything to the results thanks! dagg3r, Apr 7, 2005 Phys.org - latest science and technology news stories on Phys.org •New kind of sup
