I like to produce/prepare acid HCl, or H2SO4 in the lab from NaCl or Na2SO4 by electrochemical method. Please let me know what electrodes, ion exchange membrane, potential, and current suitable.

I am interested to use Anion exchange membrane. Acid conc. 4% is good enough for preparation. Please let me know.

Thank you

You can make chlorine gas from the first molten NaCl (above 801 C) and then electrolized liquid.. but it is dangerous, toxic, inefficient and pricey way to get some HCl and HOCl (they are products of chlorine gas and water). You will need to separate them at the end.

Search net for "electrolysis of molten NaCl".

Thank you, but I am interested to prepare acid without Cl2. by using Anion exchange membrane it is possible. But I like to know more bout what electrodes, potential and DC current (A) required.

with regards
