Copper(II) Sulfate and Sodium Hydroxide

CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4

概要

Blue copper(II) sulfate solution reacts with sodium hydroxide to form a pale blue gelatinous precipitate of copper(II) hydroxide and sodium sulfate solution. This is a common qualitative test for copper(II) ions and is used in the Biuret test for proteins.
