Does gold last forever?

    Gold, as a metal, is generally considered to be “permanent” because it is resistant to degradation by air, water, or aerobic bacteria. Pure gold, however, is very soft.  Therefore, the gold that we handle in daily life, in coins or jewelry, has mostly been alloyed, or combined, with other metals to make it stronger.  Dissolving gold requires the application of aqua regia, a specific combination of nitric and hydrochloric acids.
