uke, sok, grickalice, strpljenje i peri po čitanju !
da si pogledao link gore vidio bi ta je to potpuno drugaciji pristup i da se razlikuje od svih spomenutih na ovoj temi , te je i sama teorija potpuno drugacija...
te je na linku dokazano da mijesanje, promjena polariteta, uzrokue nastanak Aroh
ok, imaš pravo ovo je ovdje lijepo štivo za čitanje , e
Region 1 is the Initial Region where any silver hydroxide on the cathode is converted back to silver metal as described in the theory section. Also, trace contaminants that were left over from the distillation process are swept from the region surrounding the electrodes. This means few ions are entering the solution, so the conductance increases slowly at first, then faster as the initial process goes to completion.
Region 2 is the Faraday Region, where the conductance is increasing the fastest. Silver ions are leaving the anode and hydroxyl ions are leaving the cathode, but they have not reached the opposite electrodes to start combining and form silver hydroxide. (For more information, please see "Making Ions Visible", Part I and Part II)
Region 3 is the Nernst Region. The ions have reached the opposite electrodes, and are starting to combine in a very thin layer next to the electrode called the Nernst Diffusion layer. Since ions are now being lost in making silver hydroxide, the change in conductance slows down.
NoAlt
Region 4 is the Tyndall Region. The conductance has peaked, and more ions are being converted to silver hydroxide than are being released from the electrodes. This reduces the conductance, so the curve flattens or turns downward. If we shine a laser pointer through the solution, we start to see the Tyndall as the silver hydroxide particles scatter the light.
But the goal is still the same - to keep the process in the Faraday Region (#2) as long as possible, and find the optimum point to terminate the brew despite the normal variations in the process.
