300 mg of orcinol in 100 ml of conc. HCl and 0.25 ml of ferric chloride solution (10g / 100ml ).
Borsch reagent is a chemical solution commonly used in microbiology to detect the presence of indole. It is composed of hydrochloric acid, dimethylaminobenzaldehyde, and amyl alcohol. When added to a bacterial culture, the reagent reacts with indole produced by certain bacteria, resulting in a color change from yellow to red.
Sucrose. Sucrose is a disaccharide therefore does not have free electrons in the sugar to react with the Benedict reagent. Glucose has free electrons therefore shows positive with the Benedict reagent.
The reagent strip is a strip of paper impregnated with a specific chemical reagent for a chemical determination.
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
Lactose is a disaccharide composed of glucose and galactose, therefore it would react with Benedict's reagent to produce a positive result. Benedict's reagent is used to test for reducing sugars, and since lactose contains a free anomeric carbon that can reduce copper ions present in the reagent, it would give a color change from blue to brick-red precipitate upon heating if lactose is present.
Tollens reagent is composed of silver nitrate solution, ammonia solution, and sodium hydroxide solution. Silver ions in the solution are reduced to silver metal, forming a silver mirror on the inside of a test tube when aldehydes are present.

A reagent bottle is used to store and dispense chemical reagents in the laboratory. It helps keep the reagents safe from contamination and degradation. The bottle typically has a narrow neck and a lid that can be securely closed to prevent spills and ensure proper storage conditions.
molisch reagent is prepared by dissolving 5g of alpha napthol in 100 ml alcohol
Benedict's reagent can be used to differentiate glucose and maltose based on their reducing sugar properties. Glucose is a monosaccharide and will readily reduce Benedict's reagent to form a brick-red precipitate, indicating a positive test. Maltose, being a disaccharide composed of two glucose units, will also react with Benedict's reagent but may produce a less intense color change compared to glucose due to its structure.

What is the chemical composition of kf reagent
Aluminon is not a reagent. Aluminum is a metallic element.
Lactose is a disaccharide composed of glucose and galactose, therefore it would react with Benedict's reagent to produce a positive result. Benedict's reagent is used to test for reducing sugars, and since lactose contains a free anomeric carbon that can reduce copper ions present in the reagent, it would give a color change from blue to brick-red precipitate upon heating if lactose is present.
The LAL reagent water can be sterile WFI or other water that show reaction with the specific LAL reagent with which it can be used, at the limit of the sensitivity of such reagent.
