in the organic reactions for dehydrogenation alcoholic KOH is used
Chemical compounds used in laboratory are frequently called reagents.
The reagents used in the osazone test are phenylhydrazine and acetic acid. These reagents are used to detect reducing sugars such as glucose by forming characteristic needle-like crystals called osazones.
They are used to store chemical reagents in the laboratory.
hydrogen peroxide
Common reagents used in the estimation of antioxidants include DPPH (2,2-diphenyl-1-picrylhydrazyl) reagent, Folin-Ciocalteu reagent, and Trolox standard. These reagents are utilized in assays such as DPPH radical scavenging assay, total phenolic content assay, and oxygen radical absorbance capacity (ORAC) assay to measure the antioxidant capacity of compounds.
sulphuric acid
This bottle is used to contain reagents.
The reagents used in Heller's ring test are concentrated nitric acid and ferric chloride solution. After adding these reagents to a mixture containing albumin, a white ring forms at the point of contact if albumin is present.
The reagents commonly used in titration include a titrant (solution of known concentration), an analyte (solution of unknown concentration), and an indicator or pH meter to determine the endpoint of the titration. Other reagents such as solvents, buffers, and complexing agents may also be used depending on the specific type of titration being performed.
A glass bottle is used as a container for many reagents.
Group 2 reagents are used for the identification of cations such as calcium, strontium, and barium. Common reagents include ammonium carbonate, ammonium oxalate, and ammonium sulfate.
To prepare reagents used in the lab, you typically follow a protocol or recipe that specifies the amount of each chemical needed. This involves measuring out the chemicals accurately, dissolving them in the appropriate solvent, and adjusting the pH or concentration if required. It is important to label the reagents correctly and store them properly to maintain their stability and integrity.
