Regenerate: H2SO4 from NaSO4, HCl from FeCl3

[blinkman]

Make acid from NaSO4 and FeCl3. In large quantity, buying H2SO4 or HCl, transportation cost is very high. So anybody help me to make acid from that salt..? How is the process actually..?

Na2SO4 is an industrial dead end. It was discarded by bulking out laundry detergent. Look up black liquor recycle in papermills.

 

FeCl3 is discarded through water treatment, for precipitating muck when aluminum in alum is recognized as being (neuro)toxic.
