Unfortunately, there is no chemical substance with the formula CuI2. There may be a misunderstanding as Cu, Copper, has an oxidation number of +1 and +2, while I, Iodine, has an oxidation number of -1. Therefore, if this chemical substance existed, its formula would have to be CuI or Cu2I2, not CuI2.
- Definition of CuI (Copper Iodide):
1.1. This compound is commonly named Copper Iodide.
1.2. Its English name is Copper(I) Iodide.
1.3. The atomic mass of Cu is 63.55, while that of I is 126.9. Thus, the atomic mass of CuI is 190.45.
1.4. Ion structure: CuI contains Cu+ and I- ions.
- Properties:
2.1. Physical properties:
- State: CuI is solid at room temperature.
- Color: CuI is white or pale yellow.
- PH level: CuI is a solid and therefore does not have a pH level.
2.2. Chemical properties: CuI is insoluble in water but soluble in ammonia.
- Common chemical equations:
3.1. Synthesis of CuI: Cu + 2I2 -> 2CuI
- Synthesis of CuI:
4.1. Laboratory synthesis: Copper is heated in air containing iodine vapor to create CuI.
4.2. Industrial synthesis: CuI is typically produced by reacting iodine with copper, using excess iodine to prevent the formation of Cu(II), which may cause the decomposition of CuI.
