- This video shows how to make Fehling's solution, which can be used to test for the presence of glucose.
Fehling's A: copper(II) sulfate solution.
Fehling's B: potassium sodium tartrate and sodium hydroxide solution.
Poured together: Fehling's solution.
Clear video. Very neatly done and incredibly helpful. Thank you!
