在电镀镍时注意到电解液的酸度是很重要的,我们提供快速检验和改正酸度的方法,可以不需要特殊的设备。这个方法早就在实验室和我们工厂的电镀车间里用过。在20毫升滤过的电解波试样中加入0.5毫升溴甲苯酚紫的0.06%酒精溶液,如果呈蓝色,用0.1N的盐酸溶液滴至蓝色消失为止。根据我们测定的经验,如果在上述条件下消耗了2毫升的酸,那末在电解液中就不需要加酸或碱。由于镍溶液 It is important to note the acidity of the electrolyte when electroplating nickel. We provide a quick way to check and correct acidity without the need for special equipment. This method has long been used in the laboratories and electroplating workshops in our factory. 0.5 ml of 0.06% bromocresol purple alcohol solution was added to 20 ml of filtered electrolytic wave sample, and if it was blue, the solution was dropped with 0.1 N hydrochloric acid until the blue color disappeared. Based on our measured experience, no acid or base need be added to the electrolyte if 2 ml of acid is consumed under these conditions. Due to the nickel solution
