Copper(II) hydroxide is a chemical compound that has been extensively studied in the field of chemistry. It is known to decompose into copper(II) oxide and water when heated. However, the correct representation of this reaction is crucial for understanding the underlying chemical processes. In this article, we will delve into the decomposition of copper(II) hydroxide and identify the correct reactants and products.

The Decomposition Reaction

Copper(II) hydroxide decomposes into copper(II) oxide and water when heated. This reaction can be represented as:

$$Cu(OH)_2 \rightarrow CuO + H_2O$$

This equation indicates that copper(II) hydroxide (Cu(OH)2) decomposes into copper(II) oxide (CuO) and water (H2O).

Alternative Representations

However, there are alternative representations of this reaction that may seem plausible at first glance. Let's examine each of these alternatives and determine their validity.

Option A: $Cu(OH)_2 \rightarrow CuO + H_2O$

As mentioned earlier, this is the correct representation of the decomposition reaction. Copper(II) hydroxide decomposes into copper(II) oxide and water when heated.

Option B: $Cu(OH)_2 \rightarrow CuO_2 + H_2O$

This representation suggests that copper(II) hydroxide decomposes into copper(II) oxide (CuO2) and water. However, copper(II) oxide is typically represented as CuO, not CuO2. Therefore, this representation is incorrect.

Option C: $Cu(OH) \rightarrow CuO + H_2O$

This representation suggests that copper(I) hydroxide (Cu(OH)) decomposes into copper(II) oxide and water. However, copper(I) hydroxide is not a stable compound and is not typically represented as Cu(OH). Therefore, this representation is also incorrect.

Conclusion

In conclusion, the correct representation of the decomposition reaction of copper(II) hydroxide is:

$$Cu(OH)_2 \rightarrow CuO + H_2O$$

This equation accurately represents the decomposition of copper(II) hydroxide into copper(II) oxide and water when heated.

Understanding the Chemical Processes

The decomposition of copper(II) hydroxide into copper(II) oxide and water is a complex process that involves the breaking of chemical bonds. Copper(II) hydroxide is a compound that contains copper in the +2 oxidation state, which is a relatively stable state. However, when heated, the compound decomposes into copper(II) oxide and water, releasing energy in the process.

The Role of Heat

Heat plays a crucial role in the decomposition of copper(II) hydroxide. When copper(II) hydroxide is heated, the molecules gain energy and begin to vibrate rapidly. This increased energy causes the chemical bonds between the copper and oxygen atoms to break, resulting in the formation of copper(II) oxide and water.

The Importance of Chemical Equations

Chemical equations are a crucial tool for understanding chemical reactions. They provide a concise and accurate representation of the reactants and products involved in a reaction. In the case of the decomposition of copper(II) hydroxide, the correct chemical equation is:

$$Cu(OH)_2 \rightarrow CuO + H_2O$$

This equation accurately represents the decomposition of copper(II) hydroxide into copper(II) oxide and water when heated.

Applications of Copper(II) Hydroxide

Copper(II) hydroxide has a number of applications in various fields. It is used as a pigment in paints and coatings, and it is also used as a catalyst in certain chemical reactions. Additionally, copper(II) hydroxide is used in the production of copper-based alloys and compounds.

Conclusion

In conclusion, the decomposition of copper(II) hydroxide into copper(II) oxide and water is a complex process that involves the breaking of chemical bonds. The correct representation of this reaction is:

$$Cu(OH)_2 \rightarrow CuO + H_2O$$
