Determine a massa de gás hidrogênio obtida no cátodo de uma eletrólise aquosa do
Cloreto de sódio , quando uma corrente de 10 A atravessa a solução durante
16 minutos e 5 segundos.dados: (H2 = 2 g/mol) e F = 96500 C/mol.
M(gás) = K . E . i . t
M(gás) = 1 / 96500 C.mol - . 2 g.mol -/ 2 . 10 A . 965 s
M(gás) = 0,1 g.
