express the proportion of gold contained: 24 carats are pure gold, 18 carats are 75% gold, and so on. Gold forms alloys with a number of metals (see Table 2-2). Mercury wets gold particles, forming amalgams, and it is used in gold extraction operations to selectively remove gold from ground ores. Gold has a very low solubility (0.13%) in mercury.
