Fehling's solution A= concentrated aqueous solution of Copper (II) sulphate,Fehling's solution B= solution of Sodium-potassium tarterate + sodium hydroxide.
When the two Fehling Solutions A and B are mixed, a deep blue solution containing a complex cupric ion is formed. On interaction with reducing compounds such as aldehydes or sugars, the copper is...
Fehling solution "A" is copper sulphate solution and Fehling solution "B" is a solution of sodium potassium tartrate and NaOH.
