Nickel Sheet by Electrowinning from Nickel Sulfate

Electrolytic nickel is won from a nickel salt solution: pass a direct current from an inert anode through nickel sulfate solution and the nickel plates out on the cathode. A flat stainless steel plate makes a reusable cathode; when the deposit is thick enough, strip it off as a sheet of nickel. The picture: our diagram of the cell.

CC0 Isizinda Somphakathi

Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.

Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
