<p>[QUOTE=&quot;bruthajoe, post: 3950107, member: 108656&quot;]I&#039;ve been convinced to attempt to illustrate negative effects, if any, on cartwheel/luster due to this electrolytic deoxidation method. I chose a simple modern penny with moderate oxidation and for potential &quot;hidden luster&quot;.&nbsp; The penny was subject to 4 treatments(represented by images 2-4 with luster becoming more apparent with each treatment followed by two close-ups, images 6&amp;7. The first image being untreated baseline and the last image with poles reversed showing obvious destruction) all at approximately 30 second intervals while measuring the voltage across the positive cathode? and the solution. Voltage would initially be at 6-7 DC with a 4-5 volt drop during the processes.</p><p>&nbsp;This seems contrary to the common galvanic method that the <b>anode</b> is positive and <b>cathode</b> is the negative electrode. The reaction at the <b>anode</b> is oxidation and that at the <b>cathode</b> is reduction.&nbsp; The <b>positive anode </b>would attract anions toward it, while the <b>negative cathode</b> attracts cations toward it. ... In any electrochemical cell (<b>electrolytic</b> or galvanic) the <b>electrode</b> at which reduction occurs is called the <b>cathode</b>. The <b>positive electrode</b>, on the other hand, will attract <b>negative</b> ions (anions) toward itself.Jun 16, 2019</p><p>LibreTexts › chem › Bookshelves</p><p><font size="4"><b><a href="https://chem.libretexts.org/Bookshelves/General_Chemistry/Book%3A_ChemPRIME_(Moore_et_al.)/17Electrochemical_Cells/17.01%3A_Electrolysis" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://chem.libretexts.org/Bookshelves/General_Chemistry/Book%3A_ChemPRIME_(Moore_et_al.)/17Electrochemical_Cells/17.01%3A_Electrolysis" rel="nofollow">17.1: Electrolysis - Chemistry LibreTexts</a></b></font></p><p><font size="4">Very confusing to say the least but these are the results as tested with the method in reference with the coin being a&nbsp; &quot;negative anode&quot;?....</font>[/QUOTE]</p><p><br /></p>
