This is a mini tutorial showing the action of sodium meta bisulfite on Auric Chloride ( dissolved gold). The auric chloride used in this video was from my other posts on inquarting. The brown powder was dissolved into HCl-Cl as a final purification step. It took 5 washes of HCl-Cl to dissolve the approximately 11 grams of brown powder. I used 100 mL of HCl and 10 mL of Clorox per wash. Heated gently and let sit overnight after the last wash.
