BENEDICT'S TEST FOR REDUCING SUGAR

BENEDICT'S TEST FOR REDUCING SUGAR

Voiceover
Benedict's reagent is a solution of copper sulfate, sodium hydroxide, and tartaric acid. Aqueous glucose is mixed with Benedict's reagent and heated. The reaction reduces the blue copper (II) ion to form a brick red precipitate of copper (I) oxide. Because of this, glucose is classified as a reducing sugar.
