Sifat KoligatifKelas XII
CaCl₂ => Ca²⁺ + 2Cl⁻
n = 3
i = n untuk larutan elektrolit kuat shg i = 3
gr = 22,2 g
p = 200 g
Mr = (40 × 1) + (35,5 × 2) = 111
Kb = 0,52 °C / m
Tb = __ ?
ΔTb = Kb × (gr / Mr) × (1000 / p) × 3
ΔTb = 0,52 × (22,2 / 111) × (1000 / 200) × 3
ΔTb = 0,52 × 0,2 × 5 × 3
ΔTb = 1,56 °C
Tb = T₀b + ΔTb
Tb = 100 + 1,56
Tb = 101,56 °C
