Answer:

Biuret reagent is the correct answer.

Explanation:

Biuret reagent is used to test the presence of the protein in a solution.

The biuret solution contains

  • Potassium hydroxide solution.
  • Hydrated Copper sulfate.
  • Potassium sodium tartrate.

Biuret reagent is a solution that is blue in color and when it reacts with protein the color gets a change to pink-purple due presence of several peptide bonds and when there is no protein present in the solution the color remains blue.

The biuret reaction takes place when the copper II ions placed in the solution as a cupric sulfate gets reduce to copper I ions due to the presence of peptide bonds and the color change is observed from blue to violet.
