Document Summary
Lab report for the gallium(ii) salt electrochemical synthesis experiment. A 0. 960 gram of shiny silver gallium metal pieces were weighted, recorded and then placed in a small boiling tube. The boiling tube with small gallium pieces was placed on a hot plate inside a heating brick in order to melt down to liquid. A platinum electrode with rubber septum was vertically put inside the gallium boiling tube. Gallium tube along with electrode then placed in an ice water bath for about 4 minutes to cool down. As the gallium metal was cool down, it expanded in size. However, a hammer needed to break down the boiling tube since the expanding was not big enough to break the boiling tube. The final gallium electrode was a solidified gallium formed as a metal block on the tip of original platinum electrode. It was then washed with acetone and distilled water.
