Gold (Au) reacts violently with the Halogens (Fluorine, Chlorine, Bromine, Iodine and Astatine).
When both are heated, just an alloy will be formed
There are some metals which do not react with water. Metals like Silver,Gold,Platinum,copper,Mercury and non metals like Hydrogen do not react with water.
Copper, Mercury, Platinum, Silver, Gold. check the reactivity series, it may help.
Does gold rust. Gold can not rust. Rust is oxidation, and gold is inert to oxygen and even most acids. Why doesn't goldrust. Because it's a special metal iron.
silver chloride forms, which is insoluble in aqua regia, HCl, or HNO3. silver chloride is soluble in ammonium solutions but this can become very dangerous, as fulminate forms and can detonate when dried, acidifying them with HCl to precipitate the silver and form ammonium chloride solution is a safe way to handle them. insolubility of silver chloride in aqua regia is one reason karat gold is inquatered, and parted in nitric before dissolving gold in aqua regia, the insoluble silver chloride will crust over the gold (from silver in the karat gold), and aqua regia cannot dissolve the gold with an layer of silver chloride protecting the gold from the acids. some small amounts of silver chloride is soluble in aqua regia, remember soluble, or insoluble are relative terms, and can be affected by temperature, PH and so on. metal refiner Richard B.
The elements that do not react with dilute hydrochloric acid are those in the activity series below H. Those above H will react with it.
