Analytical technique involving the formation of 1:1 soluble chelates when a metal ion is titrated with aminopolycarboxylate and polyamine reagents; a form of complexiometric titration.
Industry:Chemistry
1. A test for the degree of solubility of asphalts and other bituminous materials in solvents, such as carbon tetrachloride, carbon disulfide, or petroleum ether. 2. Any test made to show the solubility of one material in another (such as liquid-liquid, solid-liquid, gas-liquid, or solid-solid).
Industry:Chemistry
An individual portion of material of a group of samples collected by a single operation of a sampling device from parts of a lot that are separated in time or space.
Industry:Chemistry
The determination of the relative or absolute age of minerals and of ancient objects and materials by measurement of their chemical compositions.
Industry:Chemistry
In paper chromatography, the wet moving edge of the solvent that progresses along the surface where the separation of the mixture is occurring.
Industry:Chemistry
The law that each ion in a conductiometric titration contributes a definite amount to the total conductance, irrespective of the nature of the other ions in the electrolyte.
Industry:Chemistry
1. A substance whose physical appearance is altered at or near the end point of a chemical titration. 2. A substance whose color varies as the concentration of hydrogen ions in the solution to which it is added varies. Also known as indicator.
Industry:Chemistry
A technique for the analysis of hydrogen; the sample is mixed with an oxidant and exploded by a spark or hot wire, and the combustion products are then analyzed.
Industry:Chemistry
In art conservation, a nondestructive digital imaging technique used to investigate underdrawings (below the painted surface) of paintings.
Industry:Chemistry
Application of the microscope to the solution of chemical problems.
