What is Pd? Important knowledge about Pd

  1. Definition of Pd
    Pd is the chemical symbol for Palladium, a chemical element in group 10, period 5 of the periodic table. Palladium was first discovered in 1803 by the chemist William Hyde Wollaston. The atomic mass of Pd is 106.4. The molecular structure of this substance is quite simple as it belongs to the type of pure chemical elements, consisting of only one type of atom.

  2. Properties of Pd
    2.1 Physical properties of Pd
    Palladium is solid at room temperature, has a silver-white color and no characteristic odor. Pd has good electrical conductivity and high durability.
    2.2 Chemical properties of Pd
    Palladium can combine with some other elements to form compounds. In particular, Pd has a high resistance to oxidation and is not oxidized at room temperature.

  3. Common chemical equations involving Pd
    Palladium participates in several important chemical reactions:

    • Reaction with Oxygen to form PdO: Pd + 1/2O2 -> PdO
    • Reaction with Hydrogen to form PdH: Pd + H2 -> PdH
    • Reaction with Chlorine to form PdCl2: Pd + Cl2 -> PdCl2

  4. Preparation of Pd
    Palladium is usually prepared from nickel ore or copper ore. In the lab, we can prepare Pd by separating Pd from its compound through a process of thermal decomposition or chemical reaction. In industry, Pd is produced through a metallurgical process from nickel or copper ore.
