Description:
Rhodium is a rare precious metal. It is a silver-white metal with a hardness
of 4~4.5 and a relative density of 12.41. The high melting point is 1966°C.
The chemical properties are stable and the main valences are +2, +4 and +6.
The first ionization energy is 7.46eV. It is also resistant to most common
acids (including aqua regia) at moderate temperatures. It can react
chemically with hot concentrated sulfuric acid, hot hydrobromic acid, sodium
hypochlorite and free halogen at 200-600 °C. Does not react with many molten
metals such as gold, silver, sodium and potassium and molten alkalis.
Platinum group metals have high melting point, high strength, stable
electrothermal properties, high resistance to spark erosion, excellent
corrosion resistance, strong high temperature oxidation resistance, and good
catalytic activity. They are widely used in automobile exhaust purification,
chemical industry, aerospace, glass fiber , electronics and electrical
industries, although the amount is small, it plays a key role, known as
"industrial vitamins" Application: - Can be placed in the classroom to stimulate students' interest in chemistry, or in the laboratory. This is a very useful tool. The Periodic Table of Chemistry is the perfect gift for teachers, students, children and science lovers. Made of real materials, will not be damaged Note: Contains no harmful elements. Some of these elements exist as simple substances, and some exist as their stable compounds. |
