Chemistry Final Exam (Answered) Oxidation Rules Rule 1: The oxidation number of an element in its free state = 0 (Also true for diatomic elements) -Mg=0,H2=0, C=0 Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion -Mg^2+=+2, Na^+=+1, O^2-=-2 Rule 3: The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. Rule 4: The oxidation numb...

CHEM 210 Exam Questions and Correct Answers What is a cathode? - Answer-a negative electrode at which reduction occurs What is an anode? - Answer-the positive electrode at which oxidation occurs Good way to remember which is which for anode and cathode - Answer-An Ox and a Red Cat What is the two electrode setup? - Answer-anode and cathode What is a galvanic cell? - Answer-A cell in which spontaneous oxidation-reduction reactions produce electrical energy (anode and cathode Zn and C...

In the analytic technique of potentiometry, a comparison is made between the voltage of one half-cell connected to another half-cell. It is customary that all half-cell potentials be compared to the potential generated by a standard electrode. This standard electrode is: a. A hydrogen electrode b. a calcium electrode c. a potassium electrode d. a copper electrode e. an iron electrode - A. a half-cell, also called an electrode, is composed of a single metallic conductor surrounded by a so...
