Document Summary
Lab 5a discussion: zn + cu^2+ zn^2+ + cu. 3: mg +2h+ mg^2+ + h2. In thermodynamics, activity is a measure of effective concentration of a species in a mixture. The species" chemical potential depends on the activity of a real solution, the ionic strength of a solution and accounts for non ideal behavior. Activity depends on all factors influencing chemical potential including temperature, pressure, etc. Activity is different by accounting for non ideal solutions with temperature and pressure influence. Activity is best used in high concentrated solutions. Liquid saturation is accounted for: cu^2+ has a configuration of [ar] 3d^9 with an unpaired electron. Zn^2+ has a configuration of [ar] 3d^10 with all paired electrons.
