摘要：

Assuming the relationship between the Ro(H) acidity function and the water activity in mineral acid concentrated solutions, iso-acidic solutions are prepared by mixing in all proportion two or three of the acids: H3P04, HC1, HCIo4, H2S04, H2SiF6. These solutions are characterized by an equal Ro(H) acidity level and different redox and complexing properties. Their Ro(H) acidity level is determined from potential measurements involving o-chloranil as an H+ indicating system and ferricinium/ferrocene as a comparison system.
