A device for measuring molecular weights by measuring the osmotic pressure exerted by solvent molecules diffusing through a semipermeable membrane.
Industry:Chemistry
The slow electrolytic generation of a soluble species which is capable of reacting quantitatively with the substance sought; some independent property must be observed to establish the equivalence point in the reaction.
Industry:Chemistry
1. Measure of the clarity of an otherwise clear liquid by using colorimetric scales. 2. Cloudy or hazy appearance in a naturally clear liquid caused by a suspension of colloidal liquid droplets or fine solids.
Industry:Chemistry
Reaction equilibrium constant for the reaction forming soluble complexes during compleximetric titration.
Industry:Chemistry
A determination of the amount of an electrolyte released during electrolysis by measuring the number of coulombs used.
Industry:Chemistry
A paper chromatography technique in which the sample is resolved by standard procedures (ascending, descending, or horizontal solvent movement) and then turned at right angles in a second solvent and re-resolved.
Industry:Chemistry
A compound whose color in the oxidized state differs from that in the reduced state.
Industry:Chemistry
An extraction process involving the introduction of a sample, all at once, into a continuously flowing countercurrent system where both phases are moving in opposite directions and are continuously at equilibrium.
Industry:Chemistry
The determination of the percentage of elements contained in a chemical substance.
Industry:Chemistry
Technique to determine the presence of combustible elements; the sample is burned with oxygen in a closed flask, and combustion products are absorbed in water of dilute alkali with subsequent analysis of the solution.
