Platinum black element symbol Pt, atomic weight 195.05.Black powder.Can absorb a large number of hydrogen at 0 ℃.Insoluble in inorganic acids or organic acids.Soluble in royal water.Used as a catalyst, gas absorbent.Platinum black can be made by burning or electrolyzing chloroplatinic acid.Black powder, soluble in royal water;Insoluble in water and inorganic acids.
The very fine powder of metal platinum is black, so it is called platinum black.Apparent density: 15.8-17.6.Dissolve in royal water.Generally, it accumulates on the surface of asbestos or other porous materials, such as asbestos, immersed in chloroplatinic acid or ammonium chloroplatinic acid solution, taken out and burned, platinum cotton can be obtained.Platinum black and platinum (stone) cotton can absorb a lot of hydrogen, oxygen and other gases and can be used as catalyst in many gas reactions.For example, the oxidation of ammonia.Electrolysis of chloroplatinic acid also enables platinum-black plating on the surface of platinum or gold electrodes, which are often used as hydrogen or other gas electrodes in electrochemistry.Platinum black can be prepared by adding zinc or magnesium to the solution of platinum salt.
