Copper is a versatile metal that has been used for centuries in various applications, including electrical wiring, plumbing, and architecture. Its unique properties make it an essential material in many industries. In this article, we will explore the chemical properties of copper metal and determine which of the given options is a chemical property.
What are Chemical Properties?
Chemical properties are characteristics of a substance that can be observed or measured during a chemical reaction. These properties are often used to identify a substance and predict its behavior in different situations. Chemical properties can include reactivity, flammability, and the ability to conduct electricity or heat.
Option A: It reacts with nitric acid to produce copper (II) nitrate.
Copper metal is known to react with nitric acid to produce copper (II) nitrate. This reaction is a classic example of a chemical property, as it involves the transfer of electrons between the copper metal and the nitric acid. The reaction is as follows:
Cu (s) + 4HNO3 (aq) → Cu(NO3)2 (aq) + 2NO2 (g) + 2H2O (l)
This reaction is a chemical property of copper metal, as it involves a change in the chemical composition of the substance.
Option B: It conducts heat.
Copper is an excellent conductor of heat, but this property is not a chemical property. Conductivity is a physical property that is related to the ability of a substance to transfer heat or electricity. While copper is an excellent conductor of heat, this property is not a chemical property.
Option C: It melts at 1085°C.
The melting point of copper is 1085°C, which is a physical property. The melting point is the temperature at which a substance changes state from solid to liquid. This property is not a chemical property, as it does not involve a change in the chemical composition of the substance.
Option D: It conducts electricity.
Copper is an excellent conductor of electricity, but this property is not a chemical property. Conductivity is a physical property that is related to the ability of a substance to transfer electricity. While copper is an excellent conductor of electricity, this property is not a chemical property.
Option E: Its reddish-orange color.
The color of copper is a physical property, not a chemical property. The color of a substance is determined by the way it interacts with light, and it is not a characteristic that is related to chemical reactions.
Conclusion
In conclusion, the correct answer is Option A: It reacts with nitric acid to produce copper (II) nitrate. This reaction is a classic example of a chemical property, as it involves the transfer of electrons between the copper metal and the nitric acid. The other options are either physical properties or not related to chemical reactions.
