Testing for non-reducing sugars
Testing for non-reducing sugars
1.When boiled with Benedict’s solution or Fehling’s’ solution, the color remains blue.
2.When boiled with HCl, the solution cooled, neutralized by NaOH, boiled Benedict’s or Fehling’s solution, the color changes from green, to yellow to orange.
HCl hydrolyses non-reducing sugars
NaOH neutralizes the excess acid because Benedict’s or Fehling’s solution does not work in acidic medium.

The subsequent time I read a weblog, I hope that it doesnt disappoint me as much as this one. I mean, I know it was my option to read, however I truly thought youd have one thing interesting to say. All I hear is a bunch of whining about one thing that you can fix should you werent too busy searching for attention.
