Silver selenates

Selivanova, Zubova, and Finkel stein [59SEL/ZUB] prepared the salt from silver nitrate and selenic acid. The product was shown to be crystalline by X-ray diffraction. The solubility product of [Pg.305]

Gelbach and King [42GEL/K1N] prepared their specimen of Ag2Se04(s) by slow precipitation from 10% silver nitrate and magnesium selenate solutions. The solubility in six solutions of selenic acid in the concentration range from 0.00 to 0.12 M was determined. Equilibrium was approached from under- as well as supersaturation. The solubility in water was found to be 2.42 x 10 M. No solubility product was calculated from the data. This has been done here with log K° = 1.75 for the protonation constant [Pg.305]

Apart from analytical errors, a possible explanation for the difference between the two sets of solubility data would be that the specimen used by Gelbach and King was not perfectly crystalline and hence had a higher solubility. As there is no obvious ground for rejecting one of the values, the review selects the mean of the two solubility products with a large uncertainty  [Pg.306]

Silver Selenate. Silver selenate, Ag2Se04, is prepared from silver carbonate and sodium selenate (see Seleniumand selenium compounds). [Pg.90]

The heat of precipitation silver selenate was measured by mixing 0.04241 moles of silver nitrate dissolved in 325 g of water with 0.02122 moles of selenic acid in an isothermal calorimeter equipped with a sensitive thermometer. The acid (7.07 M) was contained initially in a bulb that was broken in order to start the reaction. The Ag2Se04 formed was shown to be crystalline by X-ray diffraction. The water equivalent was determined after each run. The experimental results and the evaluation of the standard enthalpy of formation of Ag2Se04(cr) are shown in Table A-17. [Pg.455]

The normal sulphates usually form well-defined crystals containing water of crystallisation, and frequently exhibit isomorphism not only with one another2 but in some cases also with the corresponding selenates, telluxates and chromates. They are generally fairly soluble in water, the chief exceptions being the sulphates of barium,3 strontium and lead, which are commonly classed as insoluble, and of calcium and silver, which are sparingly soluble.4,... [Pg.173]
