2, chemical symbols of gold: AU.
. The color of the two is different:
1, platinum (platinum) color: white.
2, color of gold: yellow, golden, bright yellow.
The physical properties of the two are different:
1, platinum (platinum) physical properties: pure platinum is a glossy, extensible silver -white metal. Its ductility is the highest among all pure metals, which is better than gold, silver and copper, but its forging castability is lower than gold. The corrosion resistance of platinum metal is extremely strong, very stable at high temperature, and the electrical properties are also very stable.
The oxidation at any temperature, but it can be eroded by various halogen, cyanide, sulfur and harsh alkali. Platinum is not soluble in hydrogen chlorine and nitric acid, but it will dissolve in the water of the hot king to form chloroplastin.
2, the physical properties of gold: Strong ductility, 1 ounce of gold can be pulled into 50 miles long. Its ductility makes it easy to cast and is a good choice for making jewelry. Gold is the strongest in the metal.
This is high, which can cause extremely thin and easy to roll. 1 ounce of gold can be hammered to 4 million -foot thick and 100 square feet. The ancients hammed it into thin slices to decorate the temples and the palace. These can explain the strong flexibility and forgedness of gold.

In materials to cut gold bars or gold jewelry and observe the cut surface with magnifying glass. If you see white, you can see white Highlights, because gold and cannot be fused together, indicating that the gold is mixed with 铱.

But if it is gold jewelry, this method is not applicable because there is air in gold jewelry.
3, real gold is not afraid of fire.
This gold bars or gold jewelry burned for a while to observe its changes. Because the oxidation reaction occurs with oxygen in the air, the gold bars with insufficient purity will become gray; and the color of the pure gold will be red after the fire is baked. However, this method may be destroyed to jewelry.

The outstanding characteristics of other metals that are unable to compare with other metals: its density is extremely high, tough and wear -resistant, and it can maintain a stable nature in a variety of extreme environments. Therefore Never fade.
It, more difficult to refine platinum than gold, and high energy consumption: 10 -ton ore can only be refined into 1 ounce platinum after 8 weeks; Ore 5 days. At the same time, processing platinum requires a higher level of technology than processing gold, and each step of processing skills need to be very accurate.
