Outta curiosity, would you like me to dissolve gold with chlorine gas?
In this video we dissolve platinum using chlorine gas in hydrochloric acid. A more cost effective alternative to the more common mixture of nitric acid and hydrochloric acid or "aqua regia". To do this we simply place a vial containing a mixture of hyrochloric acid (3mL) and platinum metal powder (337mg) in a jar along with three other vials containing trichloroisocyanuric acid (3g) and 10mL of water each.
