In aqueous media, i convert nickel nitrate to nickel hydroxide for coating. I use porous nickel plate as cathode, under cathodic current nickel plate is coated with Ni(OH)2. I want to calculate amount of Ni(OH)2 but i am confused since both Ni ions in hydroxide and nitrate same state (+2).
I need to calculate theoretically then i measure the weight of coated Ni(OH)2 so that i can compare utilization of different process and experimental parameter.
Thanks in advance
If you weight it before and after, you can calculate the difference. The added weight should be Ni(OH)2. I didn't understand what is the problem.
As I understand Turan wants to calculate the theoretical meaning
Dear Ademario, as Svetlana state i want to calculate theoretically. To make it clear we can consider tüm example of electroplating of nickel. I can calculate amount of plated nickel by Faraday law [(current*time)/(Faraday Constant)]*((molar mass of nickel)/(number of exchanged Electron)]. Like in the case of nickel Electroplating, i want To calculate amount of plated nickel hydroxide theoretically. Faraday law does not work since state of nickel ion in nitrate and hydroxide is same, in other words number of exchanged elextron is zero
This question iş important for me because suppose i want to plate 2 grams of nickel hydroxide, how should i adjust current and time?
