Georgia Journal of Science

This letter is an update and review of recent activities in the Georgia Journal of Science. As of 2016, the journal has gone from a hardcopy format to a digital format through Digital Commons/Bepress (http://digitalcommons.gaacademy.org/gjs/). As a result of this, individuals worldwide now have access to journal articles free and online. Manuscripts accepted for publication are now placed online after the final acceptance and editing is complete.

A review on 20 March 2017 of online download events involving publications in 2016 shows that, of the 21 publications (the annual meeting program was included as one publication), there were …

The Use Of Ammonia As A Qualitative Test For Determining When Solid Copper Has Completely Precipitated From Aqueous Solutions Containing Copper(Ii) Ions, M. Olivia Byrd, Carl J. Ohrenberg

Georgia Journal of Science

In this study, two methods were compared to efficiently determine the absence of copper ions from a copper(II) chloride dihydrate (37.274% copper by mass) solution after precipitation using solid magnesium. In one method, a solution color change from pale blue to colorless was used as indication of a completed precipitation of copper. In the alternative method, ammonia was added to aliquots of solution which indicated remaining copper ions with a royal blue complex. For both methods, magnesium turnings were added to a blue copper(II) chloride solution until it was determined, as indicated above, that all copper had precipitated from solution. …
