Juice bottles are kept under water in cold countries to prevent them from freezing during extreme low temperatures. Water has a higher freezing point than juice, so by submerging the bottles in water, it helps to regulate the temperature and prevent the juice from freezing and expanding, which could lead to the bottles bursting.
Silver nitrate is light sensitive and can easily decompose upon exposure to light, leading to the formation of silver oxide. Storing it in brown glass bottles helps to protect it from light and prevent this decomposition reaction, preserving its stability and efficacy.
Silver nitrate is light-sensitive and can undergo decomposition when exposed to light, forming silver oxide. Storing silver nitrate in brown bottles helps protect it from light and maintains its stability and purity.
The Dicksonia tree fern will have brown fronds if they have frostbite. These fronds should be pruned in early spring before the new fronds sprout.
cause acid has a chemical reaction with metal.
Oxygen is kept in bottles to ensure its purity and prevent contamination from other gases or impurities. Storing oxygen in bottles also ensures that it can be easily transported and accessed for medical or industrial purposes.
Water is sometimes kept in colored bottles to protect it from sunlight, which can promote the growth of algae and bacteria. Colored bottles help to block out harmful UV rays and prevent the water from becoming contaminated.
I have kept vinegar in clear PET bottles for over a year and they are doing fine.
Reagent bottles are colored to protect light-sensitive chemicals or compounds from being degraded by exposure to light. The colored glass helps to block certain wavelengths of light that can cause chemical reactions or decomposition of the reagent inside the bottle.
In soft drinks, besides the carbonated water, high fructose corn syrup (and/or sugar which is better) and coloring, there is usually a flavoring agent, usually kept secret. Especially for the big names like Coke and Pepsi. Any natural or artificial flavorings are kept a secret. I have heard that Dr. Pepper's flavor is prune juice, but cannot verify this.
orange juice , water ect ...
Potassium ferrocyanide is stored in dark colored bottles and kept away from sunlight because exposure to light can cause it to degrade and increase the risk of forming potentially toxic byproducts. Keeping it in a dark environment helps maintain its stability and prevent unintended reactions.
