Hypophosphoric heteropoly blue

P-P-acid reacts with the molybdenum(V)-molybdenum(VI) reagent under the conditions of Procedures I and II to form hypophosphoric heteropoly blue, the absorption spectrum of which has two maximums at... 

Fig. 6. AbsoTption spectra of h3rpophosphoric and orthophosphoric heteropoly blue (98). A Hypophosphoric heteropoly blue, 25.9 7 as P in 25 ml. B Orthophosphoric heteropoly blue, 12.4 y as P in 25 ml.

All the results are summarized in Table VII. All the blue products obtained Avere either one or a mixture of orthophosphoric and hypophosphoric heteropoly blue. The quantities of both the heteropoly blue were calculated from the absorbances of the spectra. The final acidity... 

P-P-units in its structure, produces one or two moles of hypophosphoric heteropoly blue by Procedure I. These results suggest that all the four...
