Oxidation occurs at the electrode termed the anode and reduction occurs at the electrode called the cathode. Electrodes & Charge. The anode of an electrolytic cell is positive (cathode is negative), since the anode attracts anions from the solution. However, the anode of a galvanic cell is negatively charged, since the spontaneous oxidation at the anode is the source of the cell's electrons or negative charge.
For amphetamines, most incidents of false positives can be related to a drugâs structure, but case reports and retrospective reviews have associated many drugs with false positives.
