8. Which change to the experiment design is least likely to
improve plating efficiency? a) bringing cathode and anode closer
together b) increasing Cu(SO4)(aq) concentration c) making sure no
current is lost along the circuit d) moving cathode and anode
further away
9. All of these would result in more Cu being plated except? a)
decreasing plating time b) increasing current c) increasing plating
time d) increasing Cu(SO4)(aq) concentration
