The first experiment using HCl/Cl2 to dissolve gold.

The pressure was around 7 cm of water column at around 40ºC.

20 g of pure gold, time to dissolve ~1:30 H

* the first hose is PTFE the other ones are silicone and were thrown away after.

I like the color. How much HCl did you use?

Dave

100 mL of 6 molar HCl + ~20 mL 37% for the addition funnel

It appears that I am in love with chlorine.

Wonder if the gas house will let me order a small cylinder.
