  2. Cleaning agent - Wikipedia

    en.wikipedia.org/wiki/Cleaning_agent

    Hydrochloric acid is a common mineral acid typically used for concrete. Vinegar can also be used to clean hard surfaces and remove calcium deposits. Sulphuric acid is used in acidic drain cleaners to unblock clogged pipes by dissolving organic materials, like greases, proteins, and even carbohydrate -containing substances such as toilet tissue.

  3. Chemical drain cleaners - Wikipedia

    en.wikipedia.org/wiki/Chemical_drain_cleaners

    Acidic drain cleaners usually contain sulfuric acid at high concentrations. [1] It can dissolve cellulose, proteins like hair, and fats via acid hydrolysis. While there are many methods for unclogging drains, one of the most effective solutions is using hydrochloric acid (HCl), a powerful chemical cleaner. [2]

  5. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrochloric acid is used for a large number of small-scale applications, such as leather processing, household cleaning, [35] and building construction. [7] Oil production may be stimulated by injecting hydrochloric acid into the rock formation of an oil well , dissolving a portion of the rock, and creating a large-pore structure.

  7. Pickling (metal) - Wikipedia

    en.wikipedia.org/wiki/Pickling_(metal)

    Strong acids, such as hydrochloric acid and sulfuric acid are common, but different applications use various other acids. Also alkaline solutions can be used for cleaning metal surfaces. Solutions usually also contain additives such as wetting agents and corrosion inhibitors. Pickling is sometimes called acid cleaning if descaling is not needed ...

  8. Fracking proppants - Wikipedia

    en.wikipedia.org/wiki/Fracking_proppants

    Though sand is a common proppant, untreated sand is prone to significant fines generation; fines generation is often measured in wt% of initial feed. One manufacturer has claimed untreated sand fines production to be 23.9% compared with 8.2% for lightweight ceramic and 0.5% for their product. [ 3 ]

  9. Alkali–silica reaction - Wikipedia

    en.wikipedia.org/wiki/Alkali–silica_reaction

    Here, the silicic acid H 4 SiO 4, or Si(OH) 4, which is equivalent to SiO 2 · 2 H 2 O represents hydrous or amorphous silica for the sake of simplicity in aqueous chemistry. Indeed, the term silicic acid has traditionally been used as a synonym for silica, SiO 2. Strictly speaking, silica is the anhydride of orthosilicic acid, Si(OH) 4.
