Since electrolysis cannot occur with pure water, sodium hydroxide (NaOH) is used in the solution to provide the ions. The electrodes are made of 316 stainless steel, mostly because this is cheap ...

Electrical current is applied to water containing Na2SO4 as an electrolyte. The water is converted into gaseous ... but must be returned to the green color using 0.01M or 0.1 M NaOH or .01 M or 0.1M ...

Easy as pie. Thankfully, there’s now a more approachable method courtesy of this clever chemical hack that makes metallic sodium in quantity without using electrolysis. [NurdRage], aka [Dr. N.
