What is the pH of sulfonic acid?
Their pH values range from 1.2 to 2.5 and vary only slightly with temperature changes.
What is aromatic sulphonic acid?
Aromatic sulfonation is an organic reaction in which a hydrogen atom on an arene is replaced by a sulfonic acid functional group in an electrophilic aromatic substitution. Aryl sulfonic acids are used as detergents, dye, and drugs.
Why is sulfonic acid so acidic?
The hydrogen atom makes the compound acidic, much as the hydrogen of a carboxylic acid (see carboxyl group) makes it acidic (see acids and bases). However, while carboxylic acids are weak (with dissociation constants of about 10−5), sulfonic acids are considered strong acids (with dissociation constants of about 10−2).

What is the function of sulphonic acid in liquid soap?
Sulphonic acid is an organic acid, which is very important in liquid detergent production. It neutralizes the basic effect of sodium hydroxide (Caustic soda): It is one of the foaming agents for liquid detergent.
What Colour is sulphonic acid?
Sulfuric acid is a colorless oily liquid.
Which is more acidic carboxylic acid or sulfonic acid?
Answer. Sulfonic acid is a stronger acid compared to carboxylic acid. The main reason being the more stable sulfonate SO3- ion due to the extra oxygen atoms bonded to it compared to the CO2- ion. Sulfonic acid is stronger than carboxylic acid because of 3 oxygen in SO3H.

What is perfluorooctanesulfonic acid?
Perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS), is a man-made fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009.
