Discussion
Consider the following statements about electrochemistry.
1. Oxidation occurs at the anode in both galvanic and electrolytic cells 2. Specific conductance increases on dilution 3. One faraday deposits one gram equivalent of any substance
Answer: A
Correct answer: 1 and 3 only are correct
Statements 1 and 3 are correct: oxidation is at the anode by definition in both cell types, and one faraday deposits one gram equivalent of anything. Statement 2 reverses the behaviour - specific conductance falls on dilution, since it is measured per unit volume and dilution reduces the ions in each cubic centimetre. It is the equivalent conductance that rises.
