Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade, which is more stable in storage, is the usual form of what is described as "concentrated sulfuric acid".
Today, formulations with zeolites, polycarboxylates, citric acid, and sodium bicarbonate are among the most effective and popular substitutes for phosphates in detergent cleaning products. [26] This, along with improved water treatment processes, has greatly contributed to a significant reduction in the amount of phosphate from detergent in ...
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.

Sulfonic acids are used in many detergents. Compounds with carbon–sulfur multiple bonds are uncommon, an exception being carbon disulfide, a volatile colorless liquid that is structurally similar to carbon dioxide. It is used as a reagent to make the polymer rayon and many organosulfur compounds.

In organic chemistry, aromatic sulfonation is an reaction in which a hydrogen atom on an arene is replaced by a sulfonic acid (−SO 2 OH) group. Together with nitration and chlorination, aromatic sulfonation is a widely used electrophilic aromatic substitutions. [1] Aryl sulfonic acids are used as detergents, dye, and drugs.
It is suggested that allicin and the other sulfur compounds (including sulfuric acid) react with the chromium oxide layer, some possibly being adsorbed onto it. Washing the stainless steel soap in water would remove this layer and with it the smelly sulfur compounds. The oxide film would then reform and the stainless steel soap can be reused.
