TCCA & Co -- preliminary results
Copper sulfate and Na-DCCA give a purple/blue precipitate. The left is a small, still somewhat wet amount. The right is a dried amount, close to 2 grams. The wet amount has many darker blue spots in a lighter surrounding. Probably the difference is due to particle size. When all is ground and dried, then the color difference disappears.
Below follow pictures of cyanuric acid, crystallized from a solution in water. The cyanuric acid was made by reacting Na-DCCA with dilute hydrochloric acid and driving off all chlorine. On cooling down the crystals are formed.
