TITRASI ASAM BASA
Perhitungan
gram ekuivalen asam = gram ekuivalen basa
Va x Na = Vb x Nb
Va x Ma x a = Vb x Mb x b
4
a = jumlah ion H+ (val asam)
b = jumlah ion OH- (val basa)
Va = volume asam (L)
Vb = volume basa (L)
Na = normalitas asam (N)
Nb = normalitas basa (N)
Ma = molaritas asam (M)
Mb = molaritas basa (M)
