Q. Assertion :Sulphanilic acid migrates to anode in basic medium and to cathode in acid medium. Reason: Sulphanilic acid is a dipolar ion and exists as cation in acidic medium and as an anion in basic medium.
Answer the following. Write a reaction to bring about the …
Sulfonation: Aniline reacts with concentrated sulphuric acid to form anilinium hydrogen sulphate which on heating with sulphuric acid at 453-473K produces p-aminobenzene sulphonic acid (sulphanilic acid) as a major product. Sulphanilic acid exists as a salt; called dipolar ion or zwitter ion. It is produced by the reaction between an acidic group …

1. Introduction. Sulfonic acids (R-SO 3 H, where R is an alkyl/aryl group) form a class of important organo-sulfur compounds. Sulfonic acid (R = H) and its salts present in organic dyes provide useful function of water solubility and/or improve the wash fastness of dyes due to their capability of binding more tightly to the fabric.Sulfonic acids …
Synthesis of methyl orange from sulphanilic acid
Dissolve 6.05 g (6.3 ml, 0.05 mol) of dimethylaniline in 3.0 ml of glacial acetic acid, and add it with vigorous stirring to the suspension of diazotised sulphanilic acid. Allow the mixture to stand for 10 min; the red or acid form of methyl orange will gradually separate. Then add slowly and with stirring 35 ml of 20% sodium hydroxide …
