WebFehling’s solution in chemistry is used to differentiate between reducing and non-reducing sugars. Those sugar molecules that reduce Fehling’s solution {Cu2+ to Cu(I) oxide} are known as reducing sugars. These sugars have a free aldehyde group or the hemiacetal group that makes them reducible. They also reduce Tollen’s reagent. Example ... WebSep 9, 2024 · The Fehling A solution contain copper sulfate.The Fehling B solution contain sodium potassium tartrate and sodium hydroxide. ...
