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.
Discuss the chemical reaction between soda ash and alkyl benzene sulphonic acid
benzene sulphonic acid
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.
it is because though they act like a soap in having the cleansing properties but they have long chains of benzene sulphonic acid which the soaps don't have
React benzene with conc. H2SO4 and then with conc. HNO3. The resultant would be picric acid
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.

because the branched chain ABS are persistent in nature and cause water foaming.
Neutralize it with NaOH,add water,thickener,fragrance,preservative and colour.
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.

sodium salt of benzene carboxylic acid
Sodium chloride doesn't react with acids.
Sodium will react violently with dilute hydrochloric acid.
