Benedict’s reagent is used to detect reducing sugars, such as glucose and fructose, in food and urine. It works by reacting with copper sulfate and producing an insoluble reddish compound. The test is qualitative and can be used as a crude quantitative test. Another reagent, Benedict’s Quantitative Solution, can be used for more accurate measurements. […]
Fenton’s reagent is a mixture of hydrogen peroxide and iron that reacts with toxins in polluted water, transforming them into harmless compounds. It is commonly used to remove chemical wastes from water and improves its quality by removing discoloration and odors. The reagent works quickly and leaves little behind, but requires careful analysis to avoid […]
The limiting reactant is the substance that will be used up first in a chemical reaction, and it determines the amount of product that can be produced. A balanced equation can help determine the proportion of each reactant needed, and knowing the number of moles of each substance is necessary to determine the limiting reactant. […]
Transfection reagents are used to insert DNA into cultured cells for research purposes. They can be custom-made or purchased from life science companies and used to turn genes on or off or force cells to behave in a particular way. Various types of reagents are available, including calcium phosphate, lipid-based materials, viral DNA vectors, and […]
Griess’ reagent detects nitrites in solutions, which can be toxic in high concentrations. The reagent consists of sulfanilamide and naphthylenediamine dihydrochloride, and the color produced by the reagent indicates the level of nitrites. The Griess test is used in forensics, food testing, and medical diagnosis. Nitrites in the body can be dangerous and can cause […]
