Equation constant expressed in degrees per mole of pure solvent; used to calculate the freezing-point-depression effects of a solute.
Industry:Chemistry
An instrument used in thermogravimetry consisting of a precision balance and furnace that have been adapted for continuously measuring or recording changes in weight of a substance as a function of temperature; used in many types of physicochemical reactions where rates of reaction and energies of activation for vaporization, sublimation, and chemical reaction can be obtained.
Industry:Chemistry
Procedure for analysis of complex chemical mixtures by the progressive absorption of the components of the unknown sample (in a solvent) on a special grade of paper.
Industry:Chemistry
A phase-equilibrium technique to determine molecular weight and other properties of a solute by dissolving it in a liquid solvent and then ascertaining the solvent’s freezing point.
Industry:Chemistry
A device for the determination of molecular weights by the decrease of vapor pressure of a solvent upon addition of a soluble sample.
Industry:Chemistry
Variation of paper electrophoresis in which the electrolyte-impregnated absorbent paper is suspended vertically and the electrodes are connected to the sides of the paper, producing a current at right angles to the downward movement of the unknown sample.
Industry:Chemistry
An analytic electrochemical method in which instantaneous current reversal is imposed at the working electrode, and its potential is monitored with time.
Industry:Chemistry
A procedure for the determination of the color of an unknown solution by visual comparison to color standards (solutions or color-tinted disks).
Industry:Chemistry
A variation of paper chromatography in which an electric current is applied to the ends of the electrolyte-impregnated absorbent paper, thus moving chargeable molecules of the unknown sample toward the appropriate electrode.
Industry:Chemistry
Separation of particles according to density by employing a gradient of varying densities; at equilibrium each particle settles in the gradient at a point equal to its density.
