Ok, so... this year we have had to do discussions, as hinted at the end of the last sentence, and we're required to talk about the 'sources of error' but not 'human sources of error'. I thought all main sources of error was done by humans... can someone
Examples Of Experimental Errors
list some potential sources of error that are NOT done by humans? Back to top #2 mv_288 mv_288 Super Poster Forum Masters 14682 posts Posted 18 January 2008 - 03:50 AM it really depends. it could be the accuracy of the balances. like some measure to 1 decimal place, other round up to 3, etc. accuracy of the instruments you use for measuring. it's usually pretty hard to find error tho.

For example, if u use a string to measure how long something is, most-likely it will be inaccurate becuz the string might not be stretched out enough. So, to improve this measuring process u would go use a normal ruler lol. Sry im 2 lazy to make a better example lol Back to top #4 mommo mommo faq.asianfanatics.net AF-newbie 12 posts Posted 18 January 2008 - 06:26 AM All lab equipment, beakers, flasks, even graduated cylinders and balances all have a certain error to it, usually

Sources Of Error In Experiments
chemistry lab can arise from human error, equipment limitations and observation errors. Some other types of errors in experiments sources of errors include measurement values that are not well defined and inconsistent experiment techniques.

Equipment limitations also cause errors if instruments are not calibrated properly or if an instrument is unable to take a measurement because of calibration limitations. For instance, a digital scale that only measures https://www.reference.com/science/sources-error-chemistry-lab-e62cc6cf8f29e393 up to three decimal places is a potential limitation if a more exact measurement is needed. Instruments that are not calibrated for the conditions of the experiment also cause errors. Taking measurements during an experiment is another source of observation errors. For instance, a thermometer dipped into a hot liquid to take a measurement causes the temperature of the liquid to cool slightly. Although the drop in temperature is likely to be slight, the drop in temperature is, nevertheless, the effect of an observation error. Not all measurement values are well defined, which means that some items have a range of values rather than a single value. For instance, the mass or thickness of a piece of paper varies. It is important to be able to distinguish between the items that have variable values and the items that have definite values when conducting an experiment. It is possible to mistake an item with a variable value as an error. Finally, inconsistent sampling techniques also cause errors. Every time an experiment is done, each step must be repeated the same way as it was previously. If this does not happen, different results are likely.
