Question

what happens when aquarigia reacts with platinum​

Answer 1

Answer:

Dissolving platinum

+ 16 H+ (aq) → 3Pt4+ (aq) + 4 NO (g) + 8 H2O (l). Experimental evidence reveals that the reaction of platinum with aqua regia is considerably more complex. The initial reactions produce a mixture of chloroplatinous acid (H2PtCl4) and nitrosoplatinic chloride ((NO)2PtCl4).

Chemical formula: HNO3+3 HCl

Appearance: Red, yellow or gold fuming liquid

Solubility in water: Miscible

Density: 1.01–1.21 g/cm3
