# What are the gaseous outputs of electrolysis of Water along with NaOH or KOH?

Theoretically electrolysis of water yields Hydrogen and Oxygen in gaseous form. But to enhance conductivity we have to add an electrolyte like $$\ce{NaOH}$$ or $$\ce{KOH}$$.

Does this produce any other gases along with Oxygen? Does $$\ce{Na+}$$ or $$\ce{OH^-}$$ ions also come out as some form of gas? Or practically speaking can people breathe the oxygen which comes out of electrolysis?

What are the gaseous outputs of electrolysis of Water along with $$\ce{NaOH}$$ or $$\ce{KOH}$$?

• Per your third question: it's done that way in submarines and on the ISS. Also, you might want to break-up this question into more concise ones. There is a chance this might be close for lacking focus. May 3 at 15:56
• @ToddMinehardt all I want to know if can we breathe electrolysis generated oxygen safely. I'm concerned about electrolyte generating toxic gases. You are welcome to edit. Thanks a lot May 3 at 16:03
• @ToddMinehardt what electrolyte do they use in Submarine May 3 at 16:04
• @NilayGhosh Thank you so much. Regarding the oxygen shortage in India, can people use electrolysis on distilled water to create breathable Oxygen?? May 4 at 9:18
