Experimental thoroughness and accuracy
When performing chemical experiments in the laboratory a great deal of thoroughness and accuracy is necessary if you want to obtain reliable and reproducible results. It is important when you are performing a reaction that you measure accurate amounts of reactants to ensure the highest possible conversion, and thoroughness when you isolate your product, to minimize the loss and achieve the highest possible yield.
It is even more crucial when you are performing experiments within analytical chemistry. Here, sloppiness will not just lead to a poor yield, but can lead to a wrong conclusion to the analysis.
Below are some examples of things to be aware of:
