Verified by Experts

Fehling.s solution is a mixture of two separate solutions mixed together in equal volumes before use. Fehling (I) is an alkaline solution of potassium hydrogen tartarate (Rochelle.s salt) and Fehling (II) is copper sulfate solution. Thus Fehling.s solution is actually alkaline solution of copper (II) tartarate
