Electroconductivity Changing Tendency of Concentrated of Formic and Acetic Acids Binary Aqueous Solutions and Water-Formic Acid-Acetic Acid Ternary Solution

摘要

The specific electroconductivity (EC) of concentrated formic acid (FA) and acetic acid (AA) aqueous solutions and water-FA-AA mixtures was studied in a wide temperature range. At higher electrolyte concentration, the specific EC passes the maximum in water-FA, water-AA, and water-FA-AA mixtures containing constant AA concentration. At the (given temperature, the maximum specific EC of the studied solutions was used as a generalizing parameter. The reduced EC values (EC ratio to the maximum value at the given temperature) all over the studied temperature and concentration ranges were shown to meet in the same curves.
