Copper Synthesis Experiment
This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances, many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction, however it poses its own problems with the amount of substance that is actually yielded from the production reactions (Stathopulos, 2007). Almost no reaction has 100% yield, thus scientists inadvertently produce undesired products that must be filtered or decanted out of solution (Petrucci et al, 2007). Beginning with pure copper …show more content…
1) It was important to slowly add the NaOH to the solution to ensure that all of the solution would react with the solute. By slowly adding and stirring intermittently it allowed the most amount of solution to come in contact and solidify/thicken. If the NaOH was poured all at once, mixing the solution would become difficult as it would start to thicken immediately, thus the slow pouring ensured a uniform reaction product.
2) Bumping: is the formation of bubbles while heating a solution to its boiling point that may be harmful as they have the tendency to violently erupt.
Supernatant: is the remaining liquid left over after a precipitate has formed and settled.
Decant: is to separate a mixture, often by pouring out the supernatant to only leave the precipitate left over.
Dissolution: the process of using more chemically
