This is the Archimedes principle.
The principle behind the Kraut's test for lipids is that lipids form a white emulsion when shaken with sulfuric acid due to the formation of glycerol and fatty acids. The appearance of a white emulsion indicates the presence of lipids in the test sample.

It would be reflection, if you are doing a study island test. :)
The principle behind alkaloidal tests is based on the ability of alkaloids to form specific chemical reactions or complexes when exposed to certain reagents. These reactions can help in identifying the presence of alkaloids in a given sample by producing characteristic color changes or precipitation. Common alkaloidal tests include Dragendorff's test, Mayer's test, and Wagner's test.
the principle of this test are used the method of a qualitative test for the detection of nematode and cestode eggs and coccidia oocysts in the faeces.
Herapathite reaction is the reaction which is used to produce the complex sulfate or selenate.e.g.whe aristoquin(diquinine carbonic ester) is dissolved in hydrochloric or sulfuric acid,carbon dioxide is evolved and quinine chloride or quinine disulfate is formed,respectively.
The Keller-Kilianis test is based on the principle of iodine forming a blue color in the presence of starch. The test is used to detect the presence of reducing sugars in a solution, with the starch acting as an indicator to visually show the reaction.
The principle involved in the test for phosphate in DNA is based on the ability of phosphate ions to form a soluble complex with molybdate ions under acidic conditions. This forms a phosphomolybdate complex that can be detected using spectrophotometry, producing a blue color indicative of the presence of phosphate. This test is commonly known as the molybdenum blue assay.
same principle for latex methd
The Beilstein test is based on the principle that halogens, when burned in the presence of a copper oxide flame, form a colored flame due to the formation of copper halide salts. The test is used to detect the presence of halogens, particularly chlorine, bromine, and iodine, in organic compounds. The green or blue flame color indicates the presence of a halogen.
This is the Archimedes principle.
The basic principle involved in pauly's test is diazotization. The sulphanilic acid gets diazotised in the presence of sodium nitrite and sodium carbonate with the sample. This test answers for tyrosine, tryptophan and histidine residues. Vino.S Faculty, VIT University, Vellore, Tamilnadu.
