Biuret protein test Anhydrous copper sulfate has a strong water absorption

Biuret protein testAnhydrous copper sulfate has strong water absorption. When it is put into 95% ethanol or water-containing organic matter, it absorbs water and returns to blue crystals. The copper ions in copper sulfate can destroy the three-dimensional structure of protein and denature it. When measuring protein concentration, alkali is often added to the protein, and then copper sulfate solution is added. At this time, the solution will turn purple. This reaction is called the biuret reaction.

The reaction of copper sulfate solution and sodium hydroxide solution

According to the conditions of the double decomposition reaction, the blue copper sulfate solution reacts with the sodium hydroxide solution to generate sodium sulfate and copper hydroxide precipitate. Since the reaction is carried out in the solution, the generated sodium sulfate solution and blue copper hydroxide precipitate are colorless. Therefore, the reaction phenomenon should be described as: the solution becomes colorless and a blue precipitate is generated.

What is the difference between electroplating grade copper sulfate and industrial grade copper sulfate?

There are significant differences between electroplating grade copper sulfate and industrial grade copper sulfate in terms of purity, application fields, costs and benefits, and usage precautions. When choosing which grade of copper sulfate to use, there are trade-offs based on specific application needs and cost budget.

What are the common uses of high-purity copper sulfate?

High-purity copper sulfate has a wide range of applications and important economic value. However, due to its toxicity, it needs to be handled with caution and appropriate safety measures should be taken when using it to avoid harm to the human body and the environment.

What are the main applications of copper sulfate in industry?

Copper sulfate is widely used in industry, covering electroplating, chemistry, organic synthesis, wood preservation, coatings, analytical reagents, battery manufacturing, etc. These applications not only promote the development of related industries, but also make important contributions to the sustainable development of human society.
