Effects of temperature and solvent composition on conductometric titrations in non aqueous mixed solvents

The effects of temperature and composition of solvent mixtures on conductometric tltratbns have been lnvestlgated for the solvent system 2methoxyethand / ethane-l,2dloi. Good analytical results were obtained for a series of monocarboxylic aiiphatk and ammatk aclds and phenols by uslng 0.10 M N,N'-dlphenylguanMlne as standard titrant. Conductance titration curves, performed at -10, 25, 50, and 75 O C in the abovementioned pure solvents and in their four binarymixtures, are plesented and discussed. The peculiar behavlor of pick ackl in the lnvestlgated solvent system is emphasized in the discusslon.
