t+ =Q+¿
Q¿ ; Q = I t
volume larutan NaCl yang pindah = Al
MNaCl = nNaClV
atau nNaCl = MNaCl V
NaCl Na+ + Cl-
nNa+¿=¿ nNaCl¿¿
Q+¿=nNa+¿× zNa+¿× F ¿¿¿
Perhitungan :
V = (0,120 cm2) (6 cm) = 0,72 cm3 = 7,2 x 10-4 dm3
nNaCl = (0,020 mol dm-3) (7,2 x 10-4 dm3) = 1,44 x 10-5 mol
nNa+¿¿ yang pindah = 1,44 x 10-5 mol
Q+¿¿ = (1,44 x 10-5 mol) (1)(96500 mol-1) = 1,39 C
