An autoconductometri c est i ma ti on method is introduced based on the recordi ng of oscill a tory current i mpu 1 ses, generated duri ng neutral i za t ion events, in an unbalanced Wheatstone bridge coupled to a Wein oscillator. Toe re 1 evant e lectroni c ci rcuitory and experi menta 1 set-up is fabri cated from inexpensive, locally available components. The performance of the proposed method is checked on sixteen strong/weak acid-base neutralization systems. The overall average error of the method is rated at ± 1.5% with a precision of ± 0.5% for duplicate measurements. The data are discussed in specific relation to lower detection limit, sensitivity and electrolytic flow rates.
