Dissolve Platinum 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. Adding 1mL of hydrochloric acid (31%) to each of the vials containing trichloroisocyanuric acid begins the generation of chlorine gas. The jar is sealed to prevent the loss of chlorine. The chlorine gas reacts with the platinum metal and hydrochloric to produce hexachloroplatinic acid. This is a clean and highly atom efficient reaction in that all the chlorine and hydrochloric acid go into making the final product. There are no byproducts or side reactions. The nitric acid in aqua regia is not as efficient as it produces nitrogen oxides that bubble out and there are side reactions that waste nitric acid, requiring more to be used than what the equations would indicate. This is especially wasteful for platinum that is slow to dissolve like bulk platinum as nitric acid keeps needing to be replenished.
