Hydrofluoric acid.
Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water and is a precursor to almost all fluorine compounds. It is a colorless solution that is highly corrosive, capable of dissolving many materials, especially oxide and its ability to dissolve glass has been known since the 17th century.
Can any acid dissolve glass?
In short, acid can dissolve glass. However, only a few acids, mainly acids containing the element fluorine, are corrosive enough to properly dissolve glass. An example of this is hydrofluoric acid, which is able to react with the compound silicon dioxide found in glass, thus dissolving it.
What will dissolve glass?
Using sodium hydroxide (drain cleaner) we dissolve glass. Glass is nearly invulnerable to chemicals and thus why it’s the preferred material for chemical containers and reaction vessels. But when exposed to molten sodium hydroxide even glass will dissolve.
Which acid can decompose glass?
It is commonly used to etch glass and silicon wafers. When hydrofluoric acid comes into contact with human skin, it causes deep burns.

Does hydrochloric acid dissolve glass?
Glass is composed of silicon dioxide, a fairly unreactive material. However, glass is readily attacked by HF, but not by HCl.
Does formic acid dissolve glass?
These acids are capable of dissolving almost anything – wax, rocks, metals (even platinum), and yes, even glass.
Will sulfuric acid etch glass?
Sodium and carbon atoms on the surface of the glass are effectively eliminated by chemical etching with sulfuric acid.
Does sodium hydroxide dissolve glass?
Sodium hydroxide, aka solid drain cleaner or lye, can easily be stored in glass as a solid, but when molten, it reacts violently with glass and can actually dissolve it away!
Can hydrochloric acid etch glass?
Boiling the glass in a 36% hydrochloric acid solution for 30 min was more effective in reducing sodium, calcium, and aluminum atoms at the surface of the glass than any of the other etching methods using hydrochloric acid.
Does nitric acid etch glass?
Glass slides were chemically etched with nitric acid using five different methods.Especially, boiling the glass in a 70% nitric acid solution for 30 min is more effective in the reduction of sodium, calcium, and aluminum atoms at the surface of the glass than other etching methods with nitric acid.
Will muriatic acid eat glass?
Typically, products containing muriatic acid or phosphoric acid are best for removing hard water stains from glass. It’s important to note that this is a specialized process, because of the dangers posed by using caustic acids and you should not attempt to use these products on your own.
What does hydrofluoric acid do to glass?
Hydrofluoric acid etches glass, due to the strong bond formed between fluoride anions and the silicon molecules in glass. HF will also react with glazes, enamels, pottery, concrete, rubber, leather, many metals (especially cast iron) and many organic compounds.
Can acid damage glass?
While glass provides excellent resistance to most acids, there are three types which cause significant damage – hydrofluoric acid, phosphoric acid, and phosphorus acids. When glass is attacked by these acids, especially when they are concentrated solutions, corrosion can occur quickly.
What’s the strongest acid in the world?
fluoroantimonic acid
The world’s strongest superacid is fluoroantimonic acid, HSbF6. It is formed by mixing hydrogen fluoride (HF) and antimony pentafluoride (SbF5). Various mixtures produce the superacid, but mixing equal ratios of the two acids produces the strongest superacid known to man.
What is the pH of magic acid?
-23
Magic acid is a combination of three very strong acids, and it acts like it has a pH of -23. That’s a hundred billion times more powerful than pure sulfuric acid!
Is oxalic acid stronger than formic acid?
As we know, oxalic acid easily releases its H atom to form CH3COO− ion whereas formic acid needs more energy. Hence, the Strength of oxalic acid is more than formic acid.
Is CH3COOH an acid or base?
CH3COOH is a weak acid and dissociates partially in solution (as indicated with reversible arrow) to form H+ and CH3COO- ions. Since this is a reversible process, CH3COO- can accept H+ to form back CH3COOH. Therefore the nature of CH3COO- is basic and we call CH3COO- the conjugate base of CH3COOH.
What is stronger muriatic acid or sulfuric acid?
Sulfuric Acid (H2SO4)
of 38.5% sulfuric acid = 1.00 fl. oz. of 31.45% HCl. It takes 2% more sulfuric acid to equal muriatic acid (by volume) to accomplish identical pH and alkalinity reduction.
What acids etch glass?
Acid-etched decoration is produced by covering the glass with an acid-resistant substance such as wax, through which the design is scratched. The object is then immersed in hydrofluoric acid, or a mixture of dilute hydrofluoric acid and potassium fluoride is applied to etch the exposed areas of glass.
What chemical can you use to etch glass?
A chemical etching spray (typically hydrofluoric acid) dissolves unprotected glass areas to etch the desired image. The resist is then selectively removed, exposing the etched pattern on the glass.
Does vinegar etch glass?
Does Vinegar Etch Glass? As mentioned above, vinegar does not etch glass. Vinegar contains acetic acid, typically between 5-8%, and is actually used by many to clean glass. However, if the glass is very old, and the vinegar is very strong, there is a chance that the glass could be etched.
