- 論文の詳細を見る
The electrolytic conductivities and densities of condensed phosphoric acids have been measured in the P<SUB>2</SUB>O<SUB>5</SUB> concentration range from 55% to 80% at 55.0, 70.0, and 90.0°C. Assuming the proton jump mechanism through the hydrogen bond network of H<SUB>2</SUB>O and H<SUB>3</SUB>PO<SUB>4</SUB>, the molar conductance was calculated and found to be constant in the P<SUB>2</SUB>O<SUB>5</SUB> concentration range between 60% and 76%. The investigation has been extended to the mixtures of condensed phosphoric acids and concentrated sulfuric acid. The complex formation of [H<SUB>4</SUB>PO<SUB>4</SUB><SUP>+</SUP>·HSO<SUB>4</SUB><SUP>−</SUP>] and [H<SUB>3</SUB>O<SUP>+</SUP>·HSO<SUB>4</SUB><SUP>−</SUP>] has been suggested in the mixture.
