Web27 okt. 2024 · They include freezing point depression, lowering of vapor pressure, osmotic pressure, and boiling point elevation. The boiling point elevation is the increase of the solvent's boiling point by the addition of the solute. Potassium chloride is a salt and a non- volatile solute that increases the boiling point of the solution. WebMelting and boiling points The table shows melting and boiling points for the elements sodium to argon. The temperatures are given in kelvin, K. You can easily convert K to °C and back again: °C = K + 273 (e.g. 100 …
