pK values of molybdic acid and tungstic acid: pK values of molybdic acid and tungstic acid.Several substances are used for example 7782-91-4 and 7783-03-1 which are their cas registry numbers. Patel, Man Mohan; Agrawal, Girdhari Lal (Dep. Chem., Univ. Saugar, Sagar 470 003, India). J. Inst. Chem. (India), 55(6), 221-2 (English) 1983. CODEN: JOICA7. ISSN: 0020-3254. DOCUMENT TYPE: Journal CA Section: 68 (Phase Equilibriums, Chemical Equilibriums, and Solutions) The pK values of molybdic and tungstic acids were detd. by pH-titrn. at 40°. The pH2 values are 5.24 and 6.70, resp. .

Structure and texture of oxide nickel-molybdenum catalysts prepared in the solid phase: Structure and texture of oxide nickel-molybdenum catalysts prepared in the solid phase. Slinkin, A. A.; Kucherova, T. N.; Ashavskaya, G. A.; Nissenbaum, V. D. (Inst. Org. Khim. im. Zelinskogo, Moscow, USSR). Kinet. Katal., 25(2), 431-5 (Russian) 1984. CODEN: KNKTA4. ISSN: 0453-8811. DOCUMENT TYPE: Journal CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) There is formed a P phase of NiMoO4 in reactions of Ni(OH)2 with molybdic acids at 550°, in the course of catalyst prepn. 1313-27-5 and 7782-91-4 which are cas registry numbers of substances are two of reagents here. The formation is accompanied by an increase of sp. surface area of the system. At low relative concns. NiO:MoO3, the NiMoO4 phase behaves as structuring promotor inhibiting the annealing of NiO crystals. .
