I tried gold plated pin stripping by sodium cyanide 20gram/litre and gold stripping solution of 150ml/litre company is growel stripping.
There is no problem in dissolving gold with this solution. I cant extract the gold. After dissolving the ph is showing 14. Then i add 10 gram NAOH and add zinc dust. There is no reaction taking.
Why we add sodium hydroxide?
How and why to adjust the ph?
Thanks
