Under the action of light, nitric acid slowly decomposes into oxides of nitrogen plus  free oxygen, and may thus produce a pressure in a stoppered container. If kept for any time, the stopper should be occasionally loosened (carefully) to avoid pressure build up.

What are the uses of the reagent bottle in the laboratory?

Reagent bottles are primarily used for storing chemical solutions, reagents, and other substances in a laboratory setting. They help keep the contents protected from contamination, evaporation, and spills. Additionally, reagent bottles usually have labels to indicate the contents and provide crucial information for proper identification and handling.


What is reagent bottle and how is used?

A reagent bottle is a container designed specifically for storing and dispensing chemical reagents in a laboratory setting. They are typically made of glass or plastic, with a narrow mouth and a stopper or cap to prevent evaporation or contamination. Reagent bottles are used to safely store and dispense chemicals for experimental procedures, ensuring accurate and controlled measurements.


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.


What type of bottle is used for storing acids and bases?

Glass bottles are commonly used for storing acids and bases because they are chemically resistant and won't react with the contents. Plastic bottles made of HDPE (high-density polyethylene) can also be used for storing some acids and bases, but it is important to check compatibility before use.
