Well in today's chemistry experiment we will see how an iron wire bleeds. For this we need two chemicals. One is ammonium thiosyneate and the other is nitric acid. We also need a piece of ordinary iron wire, empty beaker and a glass of water. First place in crystals of ammonium thiosyneate in an empty beaker. And then add a bit of water to the beaker and keep stirring the mixture to prepare a clean and saturated solution of ammonium thiosyneate. Now place some nitric acid in another beaker. On the right beaker we have the nitric acid. On the left we have ammonium thiosyneate solution. Place the iron wire in the ammonium thiosyneate. And on adding a few drops of nitric acid you will see blood red color leech out of the iron wire. This chemical reaction can actually be called as bleeding of iron wire. The complex reaction between thiosyneate and iron leads to this very beautiful red color.
