How would the following changed alter the potential of the cell? 

Option for each scenario are: 
A.increase potential 
B.decrease potential 
C.no change 

1.adding Ag+ ions to the silver half reaction (assume no volume change) 
2.adding equal amounts of water to both half reactions 
3. removing Cu2+ ions from solution by precipitating them out of the copper half reaction (assume no volume change) 
4.Adding Ch2+ ions to the copper half reaction (assuming no volume change)
