After Adding Sulfuric Acid, What Copper Compound Is Present in Solution?
Copper is a versatile and widely used metallic element due to its excellent electrical conductivity, malleability, and resistance to corrosion. It is found in various compounds and minerals, and one such compound is copper sulfate. When sulfuric acid is added to a copper-containing solution, a chemical reaction occurs, resulting in the formation of a new copper compound. In this article, we will explore the process and the resulting copper compound in detail.
The chemical equation representing the reaction between copper and sulfuric acid is as follows:
Cu + H2SO4 → CuSO4 + H2O + SO2
In this reaction, copper reacts with sulfuric acid to form copper sulfate (CuSO4), water (H2O), and sulfur dioxide (SO2). Copper sulfate is a bright blue crystalline solid that is highly soluble in water. It is commonly used in agriculture as a fungicide and herbicide, as well as in various industrial applications.
The addition of sulfuric acid to a copper-containing solution is typically done to dissolve any copper compounds present. The sulfuric acid acts as a strong oxidizing agent, which helps in the dissolution of copper compounds and the subsequent formation of copper sulfate. The reaction takes place due to the displacement of hydrogen from sulfuric acid by copper, resulting in the formation of copper sulfate.
FAQs:
Q: Why is sulfuric acid used to dissolve copper compounds?
A: Sulfuric acid is a strong oxidizing agent that helps in the dissolution of copper compounds. It reacts with copper to form copper sulfate, which is soluble in water.
Q: What are the industrial applications of copper sulfate?
