If we add protein to Biuret's solution, it will turn purple. This is because Biuret's solution contains copper ions which react with peptide bonds (present in proteins) to form a violet-colored complex. Here are the steps:

1. Prepare Biuret's solution: This is typically a solution of potassium sodium tartrate, copper sulfate, and sodium hydroxide. It is initially blue in color.

2. Add the protein sample: Add the protein solution to the Biuret's solution.

3. Observe the color change: If protein is present, the solution will change from blue to purple. The intensity of the purple color is directly proportional to the amount of protein present in the solution.

4. Record your observations: Note down the color change and any other observations.

This test is a simple and effective way to qualitatively determine the presence of protein in a solution.
