Oxidation Unit Test
Consider a galvanic cell with a beaker of Chromium(III) nitrate Cr(NO3)3 and a beaker of Copper(II) nitrate Cu(NO3)2-
The Chromium(III) nitrate beaker contains a strip of chromium, and the Copper(II) nitrate cell contains a strip of copper. A wire
runs between the strips. The reaction that occurs is as follows:
2Cr(s) + 3Cu² (aq) → 2Cr³+ (aq) + 3Cu(s)
In three to five sentences, list which electrode is the anode and which is the cathode and the half reactions that occur at each
electrode.
