  1. Electrochemical studies in anhydrous formic acid

    Pinfold, T A, Pinfold, Thomas ArthurDepartment of Chemistry1956

    Although anhydrous formic acid exhibits all the properties required by a solvent for ideal polarographic characteristics, no study of the dropping mercury electrode in this medium has hitherto been described. Formic acid besides having a high dielectric constant (56.1 at. 25ᵒC) and considerable …
