Oxidation-Reduction (Redox) Reactions 1. Measuring voltage Standard potentials (E°) have been determined for how much voltage (potential) a reaction is.
Cells & Batteries. Primary Cells these cells cannot be easily re-charged; once they die… they stay dead.
Chemical Kinetics Chapter 13 13.1-13.6. Chemical Kinetics In learning chemical kinetics, you will learn how to: –Predict whether or not a reaction will.

SOLUTIONS TO EXAMPLES. Solubility of AgCl(s) in water at 25 o C is 1.274 x 10 -5 mol kg -1. Calculate the solubility of AgCl(s) in 0.010 mol kg -1 Na.
Electrochemistry [email protected] Na + Cl - NaCl Are you sure I can have that electron? I’m positive!
Standard Electrode Potentials When the concentrations of Cu 2+ (aq) and Zn 2+ (aq) are both kept at unit activity, the emf of the galvanic cell is 1.10.
1 Negative Ions - Bromine Negative ions are attracted to the positive electrode. The positive electrode is called the anode. Negative ions are called anions.
