Properties of metals:
1. Physical properties: Metallic luster, easy to conduct electricity, heat conduction zhidao, ductility.
2. Chemical properties: One of the most obvious is reducing, the second is to react with oxygen to form metal oxide, metal active order table, acid reaction and row before hydrogen element can generate hydrogen, and also can replace the less active metal, such as copper nails out 1) copper can pull wire, this is the use of the ductility of the metal;
Aluminum has a good corrosion resistance, because aluminum and oxygen form a dense oxide spot aluminum film, the chemical equation is 4Al+3O2=2Al2O3;
Iron sheet reacts with copper sulfate solution to form copper and ferrous sulfate, so when the iron sheet is inserted into the copper sulfate solution, purple red substances are generated on the surface of the iron sheet.
The chemical equation of the reaction between the copper sheet and silver nitrate solution was Cu+2AgNO3=Cu (NO3) 2+2AG. The purpose of this exploratory experiment is to explore the activity sequence of iron, copper and silver.
