What characterizes an electrolytic cell? What is an ampere? When the current applied to an electrolytic cell is multiplied by the time in seconds, what quantity is determined? How is this quantity converted to moles of electrons required? How are moles of electrons required converted to moles of metal plated out? What does plating mean? How do you predict the cathode and the anode half-reactions in an electrolytic cell? Why is the electrolysis of molten salts much easier to predict in terms of what occurs at the anode and cathode than the electrolysis of aqueous dissolved salts? What is overvoltage?

Table 17-1 lists common half-reactions along with the standard reduction potential associated with each half-reaction. These standard reduction potentials are all relative to some standard. What is the standard (zero point)? lf is positive for a half-reaction, what does it mean? If is negative for a half-reaction, what does it mean? Which species in Table 17-1 is most easily reduced? Least easily reduced? The reverse of the half-reactions in Table 17-1 are the oxidation half-reactions. How are standard oxidation potentials determined? In Table 17-1, which species is the best reducing agent? The worst reducing agent? To determine the standard cell potential for a redox reaction, the standard reduction potential is added to the standard oxidation potential. What must be true about this sum if the cell is to be spontaneous (produce a galvanic cell)? Standard reduction and oxidation potentials are intensive. What does this mean? Summarize how line notation is used to describe galvanic cells.

A) Generate a graph of ln Ksp vs 1/T (K) and find the best-fitting line. This line equation will give you the slope, which is -∆H˚/R and an intercept of ∆S˚/R. B) Determine ∆G˚ at 298K Borax is also useful as a water softener. Hard water is caused primarily by the presence of magnesium and calcium ions, which enter the water supply from minerals (calcite, gypsum and dolomite) within an aquifer. Hard water will form deposits that clog drains. Borax will react with these ions in a single replacement reaction releasing free sodium ions, which do not react with water and produce deposits. C: Write a balanced chemical equation for the reaction of Borax with calcium and magnesium ions to produce an insoluble product that will in effect, remove these ions from the water supply, thereby 'softening' the water.
