Difference between benedict and fehling test
WebBenedict's reagent (often called Benedict's qualitative solution or Benedict's solution) is a chemical reagent and complex mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. It is often used in place of Fehling's solution to detect the presence of reducing sugars.The presence of other reducing substances also gives a positive result. WebHello Friends, Here we are going to discuss the differences between the benedict Test and Fehling Test. We will discuss the differences in the reagents and i...
