how is copper 2 sulphate formed from copper oxide and sulpheric acid and why is it formed?
CuO + H2SO4 ==> CuSO4 + H2O
The reaction proceeds because the driving force is the formation of a weakly ionized material; i.e,in this case it is water. The reaction is a double replacement.
To understand how copper(II) sulfate (CuSO4) is formed from copper oxide (CuO) and sulfuric acid (H2SO4), let's break down the reaction step by step:
1. Write the balanced chemical equation for the reaction:
CuO + H2SO4 → CuSO4 + H2O
2. Identify the reactants and products:
- Reactants: Copper oxide (CuO) and sulfuric acid (H2SO4)
- Products: Copper(II) sulfate (CuSO4) and water (H2O)
3. Analyze the reaction:
In this reaction, copper oxide and sulfuric acid react to form copper(II) sulfate and water. The reaction involves the exchange of atoms between the reactants, resulting in the formation of new compounds.
The copper oxide (CuO) is a basic compound, while sulfuric acid (H2SO4) is an acidic compound. When they are combined, an acid-base reaction takes place, producing a salt (copper sulfate) and water.
CuO + H2SO4 → CuSO4 + H2O
The copper oxide reacts with sulfuric acid in a double displacement reaction, where the copper from the oxide combines with the sulfate from the acid, forming copper(II) sulfate. The hydrogen from the acid combines with the oxygen from the copper oxide to create water.
4. Understand why it is formed:
Copper(II) sulfate is formed for various purposes, including industrial, laboratory, and agricultural applications. Some common uses of copper(II) sulfate are:
- Electroplating: Copper(II) sulfate is utilized in electrolytic cells to electroplate copper onto surfaces.
- Agriculture: It is used as a fungicide to control fungal infections on crops and plants.
- Analytical Chemistry: Copper(II) sulfate is utilized in various chemical tests and experiments due to its distinctive color changes.
- Chemical Industry: It serves as a raw material for the production of other copper compounds, including pigments, dyes, and catalysts.
In summary, copper(II) sulfate is formed by the reaction of copper oxide and sulfuric acid. This reaction involves the exchange of atoms between the reactants, resulting in the formation of copper(II) sulfate and water. Copper(II) sulfate finds various applications across different industries and laboratories.
