How does fehling's test work
WebBenedict's work on analytical methods was particularly important for clinical applications. There was, for many years, a very close relationship between basic biochemistry research and biochemical clinical applications. Many biochemists were employed as clinical chemists because academic jobs as biochemists were difficult to find. WebJan 3, 2024 · It is readily affected by light, especially white light. It is also affected by moist air, being readily oxidized to nitrosobenzene. It has strong reducing power, reducing almost quantitatively Fehling's Reagent to cuprous oxide, and causing the formation of a silver mirror when warmed with an aramoniacal solution of silver oxide.
