WebTranscribed image text: Separate samples of a solution of an unknown ionic compound were treated with dilute solutions of Pb (NO3)2, AgNO3 and BaCl2. Precipitates formed … WebAfter the compound was dissolved in H2O, the conduction was tested with a voltmeter, which produced a electromotive force of 0.35 Vs turn outing that the substance is conductive since it is over 0.1 Vs. This farther proves that the unknown compound was ionic since merely ionic compounds dissociate in H2O and make an electric current.
