Other ID Marks. 1) Tarnish. On a freshly broken surface, the color is bright metallic-white. Upon prolonged exposure, it tarnishes black, brown to gray, and dark yellow.2) Silver is the best conductor of electricity. Complex Tests. Dissolves in nitric acid and and sulfuric acid.ilver can be found pure, but is usually mixed with small amounts of gold, arsenic, and antimony. A natural alloy of gold and silver is known as Electrum, and is usually classified as a variety of Gold. Silver is a very resistant mineral. It does not dissolve in most solvent s, and won't react to oxygen or water.
Naturally occurring silver is composed of two stable isotopes, 107 Ag and 109 Ag, with 107 Ag being slightly more abundant (51.839% natural abundance). Their almost equal abundance is rare in the periodic table. Silver's atomic weight is 107.8682(2) g/ mol.ilver chloride (AgCl) is precipitated from solutions of silver nitrate in the presence of chloride ions, and the other silver halides used in the manufacture of photographic emulsions are made in the same way, using bromide or iodide salts.
