It would give them a rough idea of how rich the gold is in the ore deposit. This is determined by the color of the reaction that could range from a light pink to a dark purple. The darker the purple, the richer the gold ore. This Gold Test Solution is easy to make and you should not make a lot at one time as the ‘shelf life’ is not long.
