Sep 24, 2016· Equilibria are reflections of Le Chatelier's Principle. If we begin a reaction with only the reactants, they will readily form products. As the concentration of the products increases, the rate of the reverse reaction increases. As the concentration of reactants decreases, the rate of the forward reaction decreases.

Gold readily dissolves in these solvents because of the formation of complex ions that are very stable. Gold (Au) melts at a temperature of 1,064° C (1,947° F). Its relatively high density (19.3 grams per cubic centimetre) has made it amenable to recovery by placer mining and gravity concentration techniques.
