Vol. 58 the concentration range 0.1 to 10.75 moles per liter, were measured at 25°.The apparent molal heat capacity is a linear function of ch (or m' or M'/!) only up to about a 1.5 molal solution, above which the relation found by Randall and Rossini fails. A hyperbolic second degree equation for the apparent molal heat capacity as a function of the square root of the volume concentration reproduces the specific heats with an average deviation of ±0.0075%. Values of the partial molal heat capacity of the salt at round concentrations were calculated from an equation previously derived and values of the partial molal heat capacity of the water were calculated from a new equation which is generally applicable to all molal quantities. These values are tabulated, along with those of the specific heats of the same solutions.Evanston, Illinois
Dilute ammoniummolybdate solutions gave satisfactory polarograms in a buffered solution containing sodium phosphate, potassium chloride, and citric acid. Two stages of reduction were observed. Molybdiphosphoric and molybdisilicic acids gave polarographic waves influenced considerably by the nature of the supporting electrolyte. Two stages of reduction exist, but the half-wave potentials are not well established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
