Homework Help: Chemistry

Posted by lucie on Thursday, January 11, 2007 at 10:20pm.

how do you identify an anode and cathode by direct observation in an electochemical battery when you dont have a voltmeter and the chemicals are no known.

I look on the battery for a + and - sign. In a battery, the + pole is the cathode and the - pole is the anode.
