How do you prepare Benedicts reagent?
To prepare Benedict's reagent, dissolve 17.3 g of sodium citrate and 1.72 g of anhydrous sodium carbonate in distilled water. Then add 0.5 g of copper sulfate pentahydrate and heat the solution until the salts dissolve completely. Adjust the volume to 1 L with distilled water, filter the solution if needed, and store in a cool, dark place.
What is the function of a reagent bottle in laboratory apparatus?
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.
What is the use of wide-mouth reagent bottle?
Wide-mouth reagent bottles are used to store and dispense chemicals easily due to their wide opening, which allows for easy pouring, transferring, and sampling of substances. They are particularly useful for handling viscous liquids, powders, or solid samples that may not easily fit through the narrow neck of standard bottles.
How should urinalysis reagent strips be stored and cared for?
Urinalysis reagent strips should be stored in a cool, dry place away from sunlight and moisture. Avoid exposing the strips to extreme temperatures. Keep the container tightly closed when not in use to prevent contamination.
Using dark-colored reagent bottles in storing some chemicals?
This amber/brown color is one of many pigments that are used to prevent ultraviolet (UV) light from penetrating the chemical reagent's bottle and damaging a photosensitive chemical. While there are some molecules that are affected (often very little) by the visible spectrum of colored light, UV-light is the primary range of the electromagnetic spectrum that can catalyze unwanted reactions in bottles which effectively degrades the reagent.

First, dissolve around 1 gram of phenolphthalein in a small amount of ethanol, then slowly add this to 100 mL of a 1 M KOH solution while stirring. This reagent is often used for detecting the presence of alkaline substances in various chemical tests. Always remember to label the solution and store it appropriately.
