I'm working on some platinum this week so I figured I would share some photos with the forum.
Here's a snapshot of a Pt solution to which I added a saturated solution of ammonium chloride:
Notice the distinct canary yellow color of the resulting salt.
I dissolved this Pt without using any nitirc acid or nitrate. The pregnant solution was a nice orange brown color before I added the 40 grams of ammonium chloride dissolved in 107 mL of water.
The yellow cloud formed instantly and is in the process of settling in the above photo.
I'll update this thread throughout the week.
