Shadowgraph is an optical method that reveals non-uniformities in transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function. Shadowgraph is a type of flow visualisation.

The solution is then treated with various reagents to test for reactions characteristic of certain ions, which may cause color change, precipitation and other visible changes. [ 1 ] [ 2 ] Qualitative inorganic analysis is that branch or method of analytical chemistry which seeks to establish the elemental composition of inorganic compounds ...
The Griess test tests for organic nitrite compounds; The 2,4-dinitrophenylhydrazine tests for carbonyl compounds; The iodoform reaction tests for the presence of methyl ketones, or compounds which can be oxidized to methyl ketones; The Schiff test detects aldehydes; Tollens' reagent tests for aldehydes (known as the silver mirror test)
The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulfur, in an organic compound. It was developed by J. L. Lassaigne. [1] The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety ...
Shadowgraph or shadowgram, an optical method that reveals non-uniformities in transparent media Optical comparator , a device that creates silhouettes of manufactured parts for inspection Shadowgraph, an electromagnetic and optical device once used as an alternative to magic eye tube
An example of an experiment in which spectrophotometry is used is the determination of the equilibrium constant of a solution. A certain chemical reaction within a solution may occur in a forward and reverse direction, where reactants form products and products break down into reactants.
A crucible and tongs, on a green mat. The ash content of a sample is a measure of the amount of inorganic noncombustible material it contains. The residues after a sample is completely burnt - in contrast to the ash remaining after incomplete combustion - typically consist of oxides of the inorganic elements present in the original sample.
