I cleaned my commercial water purification system with muriatic acid but I overdid it. Now there is excess muriatic acid residue. I used 6 liters of 29 % muriatic acid and further reduced with 33.6 gallons (134.4 liters) water as solvent at 1.2 % concentration of muriatic hcl.I believe the mole for the solution is 3.29 moles, is that right?
I have 99 % caustic soda flakes that I can use to neutralize muriatic acid residue. How do I go about it? How do I mix caustic soda at the right amount to neutralize the muriatic acid residue?
I'm not a chemist or a student so I would really, really appreciate your help guys. I'm on the verge of losing my small business if I don't fix this.
