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?

- 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.
