Solution for Gold Testing
For ages, gold prospectors have employed a solution of Stannous Chloride known as “Purple of Cassius” to test for the presence of gold in a solution. It would provide them with an estimate of how rich the gold is in the ore deposit. The colour of the reaction, which might range from light pink to dark purple, determines this. The darker the purple, the more valuable the gold ore.
This Gold Test Solution is simple to make, but don’t make too much at once because the’shelf life’ is short.
You will require:
Stannous chloride is a chemical compound.
Hydrochloric acid in concentrated form.
Water that has been distilled.
Bottle with a dropper.
Stirrer in glass.
To begin, add a small amount of stannous chloride to the bottle. Then pour in enough hydrochloric acid to fill half the bottle. Stir with the glass rod until the salt is completely dissolved. Fill the rest of the bottle with distilled water.
When tested with a few drops of this Gold Test Solution, gold-containing solutions turn purple.
Purple of Cassius is a purple pigment created by reacting gold salts with tin(II) chloride. It has been used to colour glass red (i.e. stained windows) and to detect the presence of gold in a sensitive chemical test.
