Larutan 0,1 mol C6H12O6, NaCl dan Na3PO4 masing-masing dalam 1000 gram air, didihkan. Pernyataan yang benar bila kenaikan titik didih ketiga larutan tersebut dibandingkan terhadap larutan Na2SO4 dengan konsentrasi yang sama adalah..
ΔTb Na2SO4 = 3/2 ΔTb NaCl
ΔTb Na2SO4 = 4/3 ΔTb Na3PO4
ΔTb Na2SO4 = 1/3 ΔTb C6H12O6
ΔTb Na2SO4 = 2/3 ΔTb NaCl
ΔTb Na2SO4 = 3/2 ΔTb molal
