Function of sodium carbonate in folin ciocalteu method

Answer 1

The colorimetric method generally used is the Folin Ciocalteu (F-C) one that consists of a rapid oxidation reaction of phenols by using alkali, generally sodium car- bonate, which yields an appreciable concentration of the phenolate ions.

Answer 2

In Folin ciocalteu method sodium carbonate plays a major role as its presence there helps in getting high yield of phenolate ions.

Folin ciocalteu method is acolometric method. in this method the fast oxidation reaction of phenols occur by the usage of alkali. And the most commonly used alkali is sodium carbonate
