Conductivities of the solutions of a number of protonic acids in ethyl acetate plotted against the composition of the solutions indicate the formation of 1:1 compounds. Their dipole moments indicate a very high polarity. This has been explained by proposing the formation of compounds of the type CH 3 COOC 2 H 5 · H + · A − . The conductivity of the solutions of tertiary bases has been explained on the basis of the formation of compounds of the type (CH 2 COOC 2 H 5 ) − BH + . Conductometric, potentiometric, and titrations using visual indicators to detect the end point have been carried out to confirm the autoprotolysis of ethyl acetate as 2 CH 3 COOC 2 H 5 rlhar2; (CH 3 COOC 2 H 5 · H) + + (CH 2 COOC 2 H 5 ) − .
