1-4 we construct the cell Voltage read on potentiometer would be -0.402 + sign means e - flow is from left to right - sign means e- flow is from right to left Line notation Cell potential = +0.799

1-6 Find the voltage of a cell if the right half-cell contains 0.50 M AgNO 3 ( aq ) and the left half-cell contains 0.010 M Cd(NO 3 ) 2 ( aq ). Write the net cell reaction and state whether it is spontaneous in the forward or reverse direction.

1-7 Because the voltage is positive, the net reaction is spontaneous in the forward direction. Cd( s ) is oxidized and Ag + is reduced. Electrons flow from the left-hand electrode to the right-hand electrode .
