Consider an electrochemical cell based on the reaction: 2H+(aq) + Sn(s) = Sn2+(aq) + H2(g). Which of the following actions would NOT change the measured cell potential?

Question

Consider an electrochemical cell based on the reaction:  2H+(aq) + Sn(s) = Sn2+(aq) + H2(g).  Which of the following actions would NOT change the measured cell potential?

lowering the pH in the cathode compartment          
		
addition of more tin metal to the anode compartment   
		
any of the changes listed here will change the measured cell potential.  
		
increasing the pressure of hydrogen gas in the cathode compartment.          
		
increasing the [Sn2+] in the anode compartment
