This chapter explains the limitations of nonaqueous acid-base titration, which involve the quantitative derivation of expressions that describe the various equilibria that are involved in nonaqueous solutions. Analysis in a nonaqueous solvent is controlled by the strength of an acid or base in the ...
The CH3COOH2+ ions produced in the reaction between perchloric acid and acetic acid are very strong proton donors to normally weak bases, therefore the titrant works as an extremely strong acid in nonaqueous solutions. With a weak base like an amine this means that the solvent/titrant combinatio...

Titrations in NonAqueous Solvents: The Relative Strengths of Acids At this point in time several major problems must be solved before the results of acid-base reactions can be predicted, even moderately well in given solvent. Theoretically, it would be desireable to be able to estimate, on ...
A study of some complexometric titrations in nonaqueous solvents "Complexometric titrations of calcium, zinc and lead with polyaminocarboxylic acids: ethylenediaminetetraacetic acid (EDTA), 1,2-diaminocyclohexanetetraacetic acid (DCTA), ethyleneglycol-bis(2-aminoethylether)tetraacetic acid (EGTA) and ....
