Cryoscopic Constant of Water measured

Kf=1.86 K⋅kg/molK_{\mathrm{f}} = 1.86\ \text{K}{\cdot}\text{kg/mol}

K·kg/molThe freezing-point depression constant of water, 1.86 K·kg/mol — one molal of dissolved particles lowers the freezing point by 1.86 °C.

Ebullioscopic Constant of Water measured

Kb=0.512 K⋅kg/molK_{\mathrm{b}} = 0.512\ \text{K}{\cdot}\text{kg/mol}

K·kg/molThe boiling-point elevation constant of water, 0.512 K·kg/mol — one molal of dissolved particles raises the boiling point by 0.512 °C.
