What does iridium react with?
Iridium makes a new substance with 5 other elements and chemicals in our lab:
- Iridium + OxygenIridium(IV) oxide Ir + O₂ → IrO₂ · When heated · Try it
- Iridium + FluorineIridium(VI) fluoride Ir + 3F₂ → IrF₆ · At room temperature · Try it
- Iridium + SulfurIridium(IV) sulfide Ir + 2S → IrS₂ · When heated · Try it
- Iridium + ChlorineIridium(III) chloride 2Ir + 3Cl₂ → 2IrCl₃ · When heated · Try it
- Iridium + BromineIridium(III) bromide 2Ir + 3Br₂ → 2IrBr₃ · When heated · Try it
It also blends into a mixture, like an alloy, with 73 other metals when melted together.
Nothing happens when it's simply mixed with 20 of the others. 21 pairings have never been tried, because not enough atoms have ever existed.
