papedudae Posted January 24, 2011 Report Share Posted January 24, 2011 Hey guys!I'm doing my chem. design lab on electrochemical cells and need to do some dilutions and have never had to use dilutions before. But anyway , is it better to do a serial dilution than to dilute from the original solution for all the different concentrations? Reply Link to post Share on other sites More sharing options...
Daedalus Posted January 24, 2011 Report Share Posted January 24, 2011 Serial dilution is (simply by the addition of absolute uncertainties) going to increase your percentage uncertainty, I think, so it's better the other way. Not as simple, though, in the lab if not on paper. Reply Link to post Share on other sites More sharing options...
