A very dilute solution of copper sulfate is used in the biuret test because it allows for the detection of proteins through the formation of a complex with peptide bonds. When proteins are present, the copper ions in the dilute solution react with the peptide bonds, resulting in a color change to violet. The dilution ensures that the solution is not too concentrated, which could lead to interference in color interpretation and false positives. This sensitivity is crucial for accurately determining protein presence in a sample.

What is the acid that reacts with copper 2 carbonate to give a blue solution?
The acid that reacts with copper(II) carbonate to give a blue solution is hydrochloric acid (HCl). This reaction forms a solution of copper(II) chloride, which appears blue due to the presence of copper ions.
How do you prepare biuret solution?
What you mean by the performance of Biuret Test? This method just can tell us that if there is any protein contents but it can't give any exact figure of the type of protein. The Beer's law is obeyed to at least 10 g per dl. So actually what your question point of? What you mean by the performance of Biuret Test?

How do you prepare magnesium sulphate in lab?
To prepare magnesium sulfate in the lab, you would typically dissolve magnesium oxide or magnesium carbonate in dilute sulfuric acid. The reaction between the magnesium compound and the sulfuric acid will form magnesium sulfate and water. The solution can then be concentrated and crystallized to obtain solid magnesium sulfate.
What is the decolorizer used in the capsule stain?
The decolorizer used in the capsule stain is a dilute solution of 20% copper sulfate. It is used to remove the purple crystal violet stain from the background and bacterial cells, leaving only the capsule stained.
How would you test the presence of sulfate ions?
To identify the presence of sulfate ions in a solution, follow these steps: To acidify the sample, add a few drops of dilute hydrochloric acid (HCl) to the sample. Then, add a few drops of dilute barium chloride (BaCl2) solution to the sample. If sulfate ions are present in the solution, a white precipitate of barium sulfate (BaSO4) will form. The reaction is: Ba²⁺ (aq) + SO4²⁻ (aq) → BaSO4 (s) For example, if we have a solution of magnesium sulfate (MgSO4), the reaction would be: BaCl2 (aq) + MgSO4 (aq) → BaSO4 (s) + MgCl2 (aq) By observing the formation of the white precipitate, we can confirm the presence of sulfate ions in the sample.
What is the reaction when water mix with copper sulfate?
Mixing these two reagents would make a dilute solution of copper sulfate.
How would you make 100cm3 of 0 01 mol dm3 copper sulfate from a solution of 0 1 mol dm3 copper sulfate?
right i dont know this 4 sure but because u want a 0.1 mol/dm3 and u only need 100cm3 u will need 0.01mols of copper sulfate to dilute in 100cm3. soo now u have a solution that is 0.01mols per 100cm3 or 0.1 mols per 1000cm3 (dm3)
What will happen if you put copper sulfate on a turtle?
Probably a very dilute solution of copper sulphate act as a desinfecting agent; but the copper sulphate is toxic. It is more sure to avoid this experiment.
If Clear dilute ammonia is added to blue copper sulfate solution does a chemical reaction happen?
Try it on your own. (Best answer for your problem is your action)
What happens when dilute sulphuric acid is poured on copper plate?
When dilute sulfuric acid is poured on a copper plate, a chemical reaction occurs where the sulfuric acid reacts with the copper to form copper sulfate, water, and sulfur dioxide gas. This reaction will cause the copper plate to dissolve and create a blue-green solution of copper sulfate. Heat and bubbles may also be observed as the reaction takes place.
How do you extract copper using dilute acid?
If you want to extract copper using dilute acid you must use sulphuric dilute acid. Pour it into a container and add some copper oxide (it's powder, I'm not sure if that's it's name) then take another container and put some filter paper on it and pour the mixture into that. It should look blue. Then add some filings into it and they should turn pink.
What is the acid that reacts with copper 2 carbonate to give a blue solution?
The acid that reacts with copper(II) carbonate to give a blue solution is hydrochloric acid (HCl). This reaction forms a solution of copper(II) chloride, which appears blue due to the presence of copper ions.
Why does protein change colour when you add copper sulphate and sodium hydroxide?
WHEN TESTED ON MILK- When milk(acid) is added with dilute Sodium Hydroxide it is mixed into an alkaline solution ,the copper sulphate is applied because the copper ions forms a purple complex with the Nitrogen from the peptide chain from the milk.The colour changes from light yellow to light purple.This proves the presence of protein in milk.
Is there a reaction between a piece of copper and dilute H2SO4.?
Yes, copper reacts with dilute sulfuric acid (H2SO4) to form copper sulfate (CuSO4) and release hydrogen gas (H2). This is a redox reaction.
What happens when dilute sulphuric acid is added to copper oxide?
When dilute sulphuric acid is added to copper oxide, a chemical reaction occurs, resulting in the formation of copper sulfate and water. The reaction can be represented by the equation: CuO + H2SO4 → CuSO4 + H2O.
What occurs when copper reacts with dilute sulphuric acid?
When copper reacts with dilute sulphuric acid, copper sulfate and hydrogen gas are produced. The copper sulfate formed will be a blue solution. This reaction is a redox reaction, where copper is oxidized and hydrogen is reduced.
What green powder do you add to dilute hydrochloric acid to make copper chloride solution and carbon dioxide?
You would add powdered copper carbonate to dilute hydrochloric acid to produce copper chloride solution and carbon dioxide gas.
