I am having a hard time washing my gold after two types of gold dissolving methods. One is where I add 70% nitric acid to computer pins to eat away at the metal causing it to release the gold. The other is when I dissolve the gold off of a new set of pins with aqua regia. Both seem to leave a lot of salts behind.
In the first method with just nitric acid the salts are so bad I end up loosing a lot of gold flakes trying to rinse the salts out. Any idea how to dissolve the salts so I can wash the gold easily? Also I would really like to know what these salts are. Is it silver chloride?
In the second method of using aqua regia on a new set of gold plated computer parts I am always left with a lot of salts that I assume are retarding the process where the liquid gold turns back into a solid and sinks back to the bottom. What are these salts? Are they the same thing as the first method? Is it silver chloride?
How can I keep the salts away.
I know my gramor is lacking. Being dyslexic is very frustrating at times.
