Common Chemical reagents used in chemistry

Common chemical reagents used in chemistry

Acetone (propanone) : An inflammable organic solvent used in extractions.

Acetic Orcein: Biological reagent, stains root tip( used in the observation of mitosis).

Agar( nutrient ): Complex sugar extracted from red algae and used to solidify a bacterial medium.

Alcohol( ethanol/ methylated spirits): Used to decolourize leaves in photosynthesis  experiments; used along with cold water, in the emulsion test for the ppresents of lipids(fats). A clody white suspension indicates a positive test result; this substance is flammable.

Ammonia solution:  Used in qualitative analysis experiments to detect the presence of some cautions.

Aniline Hydrochloride: Biological reagent, lignin(wood) stains yellow.

Barium chloride / nitrate: Reagents used in qualitative analysis to detect some cautions in solution.

Benedict's solution/ Fhehling's solution: Tests for simple or reducing sugars like glucose. A change in color from blue to green to yellowish to red is seen. A red precipitate is formed.

Bicarbonate indicator solution: Used in photosynthesis and respiration experiments. It identifies changes in CO2 concentration.

Biuret reagent: Used in biurette test for the presents of proteins. A purple color indicates a positive test result.

Borax carmine: Biological reagent, used to stain mounts of animal material. Nuclei stain pink.

Bromothymol Blue solution:  pH indicator (range 6.0 to 7.6); Used in respiration experiments; it turns from blue to yellow or green, if CO2 is present.

Bromine: A bown toxic gas. It is used to demonstrate diffusion of gases. It is used as a bench reagent in chemistry.

Calcium Chloride: A drying agent used in dessicators.
