Caption: Protein test. Conical flasks containing negative (left) and positive (right) tests for proteins using copper (II) sulphate solution (light blue, left). The peptides in the protein form a complex with the copper (II) ions (replacing the water molecules that were present), turning the solution a deep blue colour.
