TNT Posted March 4, 2010 Report Share Posted March 4, 2010 I am doing my biology laboratory report. Can literature values just be values obtained by a university undergraduate who had done a similar experiment or does it have to be from a journal?

Hedron123 Posted March 4, 2010 Report Share Posted March 4, 2010 The literature value is the result that you should have obtained if the experiment was free of error. For instance:Mg(s) + 2HCl(aq) ====== MgCl2(aq) + H2(g)If this reaction was carried out free of error, you would obtain 1 mole of hydrogen gas. One mole of any gas will have a volume of 22.4dm3. However, if you carried out the experiment under normal conditions in a school lab, you would obtain a lower volume of gas. Hence, the experimental value (the one you obtained) will be lower than the literature value (theoretical value) and the difference between the two is due to the errors of the experiment.
