What is an HF molecule?
An HF molecule is composed of one hydrogen atom bonded to one fluorine atom. It is a colorless and odorless gas at room temperature. HF is classified as a weak acid and is commonly used in industrial processes such as etching and cleaning of metals.
What acid cannot be kept in glass containers?
Hydrofluoric acid is an acid that cannot be kept in glass containers because it reacts with silica in the glass to form silicon tetrafluoride and water, weakening the container and potentially causing it to break. This reaction can release toxic fumes and lead to leaks.
What physical state is HF at room temp?
HF is a very corrosive gas at room temperature. It can even etch glass!
Can a bottle hold hydroxide?
It depends what the hydroxide is; but common hydroxides (Sodium and Calcium hydroxides for instance) can be stored in glass bottles short-term. However, they do attack glass slowly, and equipment that is in regular contact with them can be damaged: burettes made of glass often sieze up after repeated use with these substances. Because of this slow but significant reactions, it is now more normal to see hydroxides stored in plastic bottles.

Hydrofluoric acid is stored in a glass bottle for a long time what happens?
The glass bottle is destroyed; the silicon fluoride is formed.
Resistant to HF?
Dropper Bottle
Why should liquid medication be stored in glass bottles?
Medications stored in glass containers are usually liquid. These medications are better stored in glass due to how they sometimes react to the plastic of the other containers. Also, some of these glass containers are known to be darkened, in order to help preserve the medication in the bottle.
Why is beer always served in glass bottles and not in plastic ones?
Beer Is Stored In A Glass Bottle Because, If You Stored It In Plastic You Could Taste A Plastic Taste Off It And Also Glass Get Colder Quiker Than Plastic.
PFA Reaction Bottle?
Resistance to HF
Used in the etching of glass?
HF, Hydrofluoric acid.
How do you make a thermos flask model?
Take a metal cylinder, and place a spring in the bottom (as a shock absorber). Inside the metal cylinder, sitting atop the spring is a glass bottle. Between the cylinder and the bottle (around the sides and the bottom of the glass bottle) is a vacuum. Both the vacuum and the glass serve as insulators for anything that is to be stored in the glass bottle. This means that, if you store something warm in the inner glass bottle, it will be very difficult for the heat to conduct through the glass AND the vacuum...and the material will stay warm. If you store something cold in the bottle, it will be very difficult for heat to conduct through the cylinder, the vacuum, and the glass...and the material will stay cold.
How get glass stopper out of a glass bottle?
Grease the top of the bottle!
Why are acid stored in a glass containers rather than plastics?
Acids are now stored in plastic containers. There are some advantages to plastic. First, plastic won't break if you drop it on the lab floor. Second, there is an acid (hydrofluoric acid, which is always called HF because "hydrofluoric" and "hydrochloric" sound a lot alike but "hydrofluoric" is far more dangerous) that can't be stored in glass at all. HF will eat right through a glass container. It can be, and is, stored in plastic. Having said that, no one in an educational setting should ever have access to this product. Do an exercise here: draw a square 125mm on each side. If HF comes into contact with that much of the skin on your body, you will die without EXTREMELY aggressive medical care from people who know how to manage HF casualties. And even if your medical attendants have been to Honeywell's school - Honeywell is the company that makes most of the HF in the United States - and they have all the chemicals needed to save your life, there are no guarantees. Next, plastic containers weigh less. And they can be made with a roughened surface for better gripping.

Will fluoride react with borosilicate glass?
Yes, glass doesn't resist to HF and other compounds of fluorine.
