Highest cryoscopic constant
Did you know?
WebIts technical name is the cryoscopic constant. The Greek prefix cryo- means "cold" or "freezing." In a more generic way, it is called the "molal freezing point depression constant." The constant called the van 't Hoff factor is symbolized with the letter 'i' and is discussed below the example problems. These are some sample cryoscopic constants: WebOsmotic pressure is a colligative property of solutions that is observed using a semipermeable membrane, a barrier with pores small enough to allow solvent molecules to pass through but not solute molecules or ions. The net flow of solvent through a semipermeable membrane is called osmosis (from the Greek osmós, meaning “push”).
