MOLECULAR CONDUCTIVITY OF AMIDOSULPHOXIC ACID. 



263 



The molecular conductivity of ami dosul phonic acid for the 

 respective dilutions, /^, are, therefore, — 



The molecular conductivity of the acid at infinite dilution, /^ x , 

 has heen calculated from that of the sodium salt. 



Molecular conductivity of sodium amidosulphonate. A solution 

 of pure sodium hydroxide, prepared from metallic sodium, was made, 

 titrated with pure and crystallised oxalic acid, and made up to -q^- A r , 

 phenol-phthalein being used as the indicator. About 30 c.c. of this
