Answer to Question #76975 in General Chemistry for S.SH.D

Question

what are the sources of errors in the experiment of determination of the composition of NaHCO3 by gas evolution analysis

Answer 1

A source of error is any factor that may affect the outcome of an experiment. There are countless conceivable sources of error in any experiment; you want to focus on the factors that matter most. Identify each source of error specifically and then explain how that source of error would have affected the results. Keep in mind that an "error" to a scientist does not mean "mistake"; it more closely means "uncertainty".

The main source of random errors is the human factor. People makemistakes all the time. An error can sometimes lead to a very bigmistake when the error is not corrected.
