( bar )
Small bars of
high purity (99.9%) Gold metal (atomic number 79).
Ideal for element collectors of those conducting experiments/producing
alloys with pure Gold metal.
Compared with other metals, Gold is the least chemically reactive of
all, but can be dissolved in Aqua Regia (a mixture of Nitric &
Hydrochloric Acids). Gold dissolves in Mercury, forming amalgam alloys,
but does not react with it. Gold is the most malleable and ductile of
all metals; this single 1/2 gram bar can be beaten into a thin 2 foot square
sheet. Chemically, it is unaffected by air, moisture and most corrosive
reagents. Gold also strongly reflects infrared radiation. Its melting
point is 1947.52 °F (1064.18 °C.). Available in small thumbnail size
ingots as shown above. Weight & purity are certified.
