INSOL IN WATER, ACID; SOL IN POTASSIUM CYANIDE, HOT SULFURIC ACID;Soluble in aqua regia, insoluble in acids;Dissolves readily in 3:1 hydrochloric-nitric acid to form HAuCl4; dissolves in cyanide solutions in the presence of air or hydrogen peroxide to form Au(CN)2
Application
Gold based neutron flux monitors may use gold foils. Au foils may be used to form a AuSn/Au joint system for opto-electronic chips. Modified gold foil electrode may be used to study heterogeneous electron transfer properties of biological electron transfer proteins.3 Electrodeposited polycrystalline palladium-nickel alloy on gold foils may be investigated for the enhanced catalytic behavior of the alloy.
