- LManufacture in which all the materials used are: electrolysis (Salze-83)In the the following Text of the text to be The LOats and oats Vip2-a)-Vip2 , Vip2-b)-Vip2 , Vip2-c)-Vip2 and so on. meaningful Filled will be.
Submersion It's two Graphite electrodes in One Zinc-coding solution and laying One Balanced voltage to, This is it. flowing a Electrical Electricity. On the The Electrodes, The with to the Minuspol Connected is, It is The Commission Manufacture from materials of any heading Zinc and to The Electrodes, The with to the In addition Connected is, is divorced The Commission Iodine from. The in The Lthe island of which: Operations will be Now . more accurately Considered.
In The Zinc-coding solution diving two Electrodes. One of them. of which: is with to the Minuspol Head of Connected, They is by means of Vip2-a)-Vip2 loaded. This Electrodes will be Vip2-b)-Vip2 Called. You has One Surplus of electrons and withdraws Therefore, Vip2-c)-Vip2 Ions to. This Ions designated It's as Vip2-d)-Vip2, In the Example are It 's Zn2+-Ionen. From The Separation of Zinc to The Vip2-e)-Vip2 can It's closing, that The Zinc ions to The Catheter Vip2-f)-Vip2 to take up and to Vip2-g)-Vip2 will be. Zn2+ + Vip2-h)-Vip2 → Vip2-h)-Vip2.
The with to the In addition Related Electrodes will be Vip2-A)-Vip2 Called, They is Vip2-B)-Vip2 loaded. You has Lack of electrons and withdraws Therefore, Vip2-C)-Vip2 to. This Ions will be Vip2-D)-Vip2 Called. In the Example are It 's I– -Ⅰons (Iodides and their salts). On the The Anode to give These The Commission Vip2-E)-Vip2 from and will be to Iodine atoms, The The Commission to of a width of not more than 30 mm Vip2-F)-Vip2 connecting. On the The Anode shows The Commission Therefore, This brown Iodine.
