Will lye 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!

What chemical can dissolve glass?

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.

What acids will dissolve glass?

Generally, acids that can dissolve glass are those containing the element fluorine. This is due to the chemical ability of fluorine to break silicon dioxide bonds found in glass. Examples of acids that can dissolve glass are hydrofluoric acid, fluorosulfuric acid and fluoroantimonic acid.

Can caustic soda dissolve glass?

Using sodium hydroxide (drain cleaner) we dissolve glass. … But when exposed to molten sodium hydroxide even glass will dissolve. To perform the reaction a steel container is used as it’s resistant to the sodium hydroxide.

Is NaOH corrosive to glass?

Sodium hydroxide corrodes silicate glasses of all compositions to a greater extent than all the other hydroxides.

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.

Does anything react with glass?

Glass is resistant to most acids but is highly susceptible to attack by alkaline materials, especially a concentration of OH ions giving a pH greater than 9.0. The result is an attack of the network forming silica-oxygen (Si-O) bonds, leading to dissolution of the glass surface.

Will Drano etch glass?

Drano. Dissolving glass is a pretty amazing trick we covered in this article. We used sodium hydroxide to eat away and dissolve a glass jar. Sodium hydroxide is the main ingredient in Drano and other solid drain cleaners.

How do you make hydrofluoric acid?

Hydrofluoric acid (HF) is produced by the reaction of concentrated sulfuric acid with fluorspar (calcium fluoride): CaF2+H2SO4→2HF+CaSO4.

Does NaOH etch glass?

NaOH was more reactive than KOH with E-glass fibres; at times we found NaOH to etch glass fibres up to twice the magnitude of KOH. Increasing the concentration and temperature of the alkaline solution resulted in an increase in the reaction rate.

What does Lye do to glass?

The liquid lye eats away at both the inside and the outside of the glass. The sodium hydroxide and the silicone dioxide in the glass react to form sodium silicate. In heated liquid mixture, this new sodium silicate dissolves away leaving only a hole in the glass.

What is in caustic soda?

Caustic soda is the chemical compound sodium hydroxide (NaOH). This compound is an alkali – a type of base that can neutralize acids and is soluble in water. Today caustic soda can be manufactured in the form of pellets, flakes, powders, solutions and more.

Does potassium hydroxide react with glass?

Re: Can potassium and sodium hydroxide (KOH and NaOH) react with glass? The intersting thing is that the Na and the K both start and end the reaction as ions in solution so there shouldnt be any difference in the energy changes. In both cases the reaction is hydroxide ions + glass gives silicate ions.

Does potassium hydroxide etch glass?

By etching the glass with potassium hydroxide, the modified material can be removed.

What is lye powder?

Lye” most commonly refers to sodium hydroxide ( ), but historically has been used for potassium hydroxide ( ). Today, lye is commercially manufactured using a membrane cell chloralkali process. It is supplied in various forms such as flakes, pellets, microbeads, coarse powder or a solution.

How do you make KOH?

Dissolve 66 g. KOH pellets (85% KOH) or 56 g. anhydrous KOH in about 80 ml. distilled water, cool and dilute to 100 ml.

How do you make soap lye?

To make lye in the kitchen, boil the ashes from a hardwood fire (soft woods are too resinous to mix with fat) in a little soft water, rainwater is best, for about half an hour. Allow the ashes to settle to the bottom of the pan and then skim the liquid lye off the top.

What is lye soap?

Lye is a very-alkaline product that is used to make soap, but it is also used in the food and cleaning industries. There are several types of lye, the most known and most commonly used being NaOH, sodium hydroxide, and KOH, potassium hydroxide.

How do you make NaOH?

Dissolve 1 tablespoon (17 grams) of salt in 1.24 cups (290 mL) of water. Add the water to a glass and gently pour the salt into the water. Stir it in well with a spoon until the salt is completely dissolved. If your cup has a lid, attach it after adding the salt and shake it up and down to mix the salt it in.

Is baking soda sodium hydroxide?

Complete step-by-step answer:- Sodium hydroxide is not known as baking soda. Baking soda is another name for sodium bicarbonate. – Sodium hydroxide comes from carbonate sodium, formerly known as ‘caustic soda’. There is no danger with sodium hydroxide.

Can you buy sodium hydroxide?

You can find sodium hydroxide online. You can purchase it at Amazon as sodium hydroxide or lye, pure lye drain opener, caustic soda, and pure or food-grade sodium hydroxide. Depending on your project, you may be able to substitute potassium hydroxide (KOH), which has similar chemical properties and is easier to find.

Is baking soda same as caustic soda?

caustic soda is another name of sodium hydroxide . it is used in soap and detergents while baking soda is a cooking soda I.e sodium bicarbonate.

Does vinegar neutralize caustic?

Will vinegar neutralize sodium hydroxide? Never, never, NEVER use vinegar on a lye splash anywhere on your body. Rinse with plenty of plain cool running water. Vinegar, an acid, does indeed neutralize NaOH or KOH, both bases, but there are serious downsides to doing this kind of chemistry directly on the body.

Can you mix caustic soda and vinegar?

The reaction can be violent and may damage the pipes, could release harmful gases or may not work at all because only a small portion of the blockage is exposed to the vinegar. It’s dangerous to combine caustic soda with any other chemicals in your drain, even hot water, because of the amount of heat released.
