Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. In essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. Suppose a current of 0.630 A is passed through an electroplating cell with an aqueous solution of Ag₂SO4 in the cathode compartment for 28.0 seconds. Calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol. 0 0.0 X H

It may be helpful to revisit the phase diagram for water in this section: https://serc.carleton.edu/details/images/10201.html 1. How does the Gibbs energy change as the pressure is increased? Recall that dG = Vmdp 2. Sketch a plot of the Gibbs energy vs. the pressure for liquid and solid water. The point where the lines intersect represents a phase transition. (Hint: consider how the molar volume of ice relates to the molar volume of water). AG P 3. The Gibbs energy of a pure substance is identical to another thermodynamic quantity: the chemical potential, μ. How does the chemical potential of liquid water relate to the chemical potential of solid ice at standard pressure (1 bar)? How does this change at high pressure?
