Lampiran 1 Perhitungan pembuatan gas H2S
FeS + 2HCl FeCl2 + H2S
0,0006 mol 0,0012 mol 0,0006 mol 0,0006 mol
Berdasarkan hukum kesetimbangan reaksi untuk gas, diketahui bahwa pada T dan P yang sama, 1 mol gas tertentu sama dengan 20 L.
1 ppm H2S = 1 mg/L = 20 mg/20 L M = gram/Mr
= 2x10-2/34
= 0,00058 ~ 0,0006 mol Bobot FeS yang diperlukan M = n x Mr
= 0,0006 mol x 88 gram/mol = 0,0528 gram ~ 0,05 gram Volume HCl 1 M yang diperlukan V = n x M
= 0,0012 mol x 1 L/mol = 0,0012 L
