Caption: Biuret test for proteins. The Biuret reagent contains copper(II) sulfate (CuSO4) and sodium hydroxide (NaOH), with potassium sodium tartrate (KNaC4H4O6) added to stabilize copper ions. Here a pipette is used to add blue-coloured Biuret reagent a solution of albumin (egg white) in a beaker. The solution turns violet (deep purple), indicating presence of proteins.
