Sulfonic acid usually refers to a member of the class of organosulfur compounds with the general formula RS(=O)2-OH, where R is an alkyl (-CnH2n+1) or aryl (-C6nH6n-1).
The formal part of acid, HS(=O)2-OH, are formally derivatives of the "parent" inorganic compound with the formula HSO2(OH) ( = sulfurous acid H2SO3)
The chemical formula of detergent made from soda ash (sodium carbonate) and alkyl benzene sulfonic acid typically involves a combination of these two components to form a surfactant molecule. The exact formula would depend on the specific alkyl chain length and structure of the alkyl benzene sulfonic acid used in the synthesis process.
Titration with strong base requires eg. methyl red, changing to yellow at 6.2, but it endpoint may come too early when the sulfonic acid is weaker than acetic acid: OK if pKa < 4.5 .So it's safer to use phenolphaleine (purple at pH=8.5) for acids with pKa < 8
The specific heat of linear alkylbenzene sulfonic acid is approximately 0.71 J/g°C.
toulene+sulphuric acid = o-methyl benzene sulphonic acid + p-methyl benzene sulphonic acid. Since methly group is ortho and para directed group so it activates benzene ring for electrophilic substitution reaction.
Whenever two compounds have the same cation or same anion they can not form a new compound and therefore chemical reaction does not take place, benzene sulphonic acid and its salt have the common anion so do not react with each other.

It is considered to be an organic chemical.
You react oil with Sulphur Trioxide via falling film reactor or react oil with Oleum (very strong Sulphuric Acid) in a CSTR reactor. The name of the process is Sulphonation or Sulfonation depending on English or American spelling style.
sulphonic acid is the active material for almost all synthetic detergents.

Hi, citric acid an formic acid are the most common replaces for acetic acid in the textile industry.

I believe the question mean the sulphonic acids. The sulphonic acids are pre-finished of the surfactants and will need future reaction with caustic soda. They are acidic, highly viscous and can do reduce surface tension as the way surfactant do but a lot stronger with pH value approximately 2-3. Most common sulphonic acids is Linear Alkyl Benzene sulphonic acids.

because the branched chain ABS are persistent in nature and cause water foaming.
