自然电流法所用的不极化电极在放置一段时期不用以后,由于瓷杯底部的孔隙被硫酸铜的晶体所堵塞,硫酸铜溶液不能向外渗透,电极的电阻很大。为了降低电阻,以往的办法是将电极放在盆里用
Natural current method used in the non-polarized electrode is not placed for a period of time, as the bottom porcelain cup by the copper sulfate crystal blockage, copper sulfate solution can not be infiltrated, the electrode resistance is large. In order to reduce the resistance, the past approach is to use the electrode in the basin
