首先,取一只已经用过了的电池里面的炭棒作为阳极,以径为0.2厘米左右的粗铁丝作为阴极,在粗铁丝外再套一个口径约为1厘米的玻管,然后将此二电极用导线缠好,把它们分别固定在铁架台的两根支杆上,导线的他端分别联接在一个6伏特的蓄电池的两极上,同时取一个坩埚或蒸发皿作为电解池,并把它适宜的装在铁架坏上。以后取十克的亚硝酸钠装入电解池中,在电解池下用喷灯加热,三、四分钟后即可融化。此时取一个穿孔的石棉钢,把十克的氯化钠放在穿孔石棉网的周围,然后把它小心的盖在电解池上,并且慢慢的把氯化钠加入电解池中,这是为了防止氯化钠向
First of all, take an already used battery inside the carbon rod as the anode, with a diameter of about 0.2 cm thick wire as a cathode outside the thick wire and then set a diameter of about 1 cm glass tube, and then the two The electrodes were wrapped with wires and fastened to the two legs of the iron stand respectively. The other ends of the wires were respectively connected to the two poles of a 6-volt battery. At the same time, a crucible or evaporating dish was used as an electrolytic cell and the electrode Fitted on the iron frame on the bad. After taking ten grams of sodium nitrite into the electrolytic cell, the electrolysis cell with a torch heating, three or four minutes to melt. At this point, take a perforated asbestos steel, place ten grams of sodium chloride around the asbestos net and place it carefully over the cell and slowly add sodium chloride to the cell in order to Prevent sodium chloride from going
