Iron Sulfide Detection Solution

Observe the following procedure to use the Iron Sulfide Detection Kit: 1. Take a 6" length of armor, cut into 1/2" lengths and place it in a polyethylene titration dish. 2. Drop several drops of Iron Sulfide Detection Solution on the armor. Foaming will occur if the zinc coating is still present on the armor wire. 3. If a bright yellow precipitate (arsenic sulfide) is formed, iron sulfide is present on the armor. 4. If the sample is so oil wet that the detecting solution cannot penetrate it, add a few drops of the foaming agent to water wet the sample. If the sample is paraffin coated, heat may have to be applied to obtain a test. 5. Wash and dry the titration dish. Store the articles back in the box.
