Simple Method to Detect Palladium Materials Needed: • Nitric acid (HNO3) • Hydrochloric acid (HCl) • Aqua regia (1 part nitric acid 3 parts hydrochloric acid) • Stannous chloride solution (SnCl2 dissolved in a little warm HCl) • Dimethylglyoxime (DMG) • Hot water • Clean test tube Test 1 (Using SnCl2): • Dissolve the suspected sample in aqua regia (1 nitric 3 hydrochloric). • Boil until the solution becomes thick, like syrup. • Add the same volume of water. • Filter the solution. • Place 1–2 dro
