Q: What is the freezing point depression constant (Kf) for water?
Solution: The freezing point depression constant (Kf) for water is 1.86 °C kg/mol.
Steps: 4
Step 1: Understand what Kf means. Kf is a constant that tells us how much the freezing point of a solvent (like water) decreases when a solute is added.
Step 2: Know that for water, this constant is specifically measured in degrees Celsius per kilogram per mole.
Step 3: Remember the value of Kf for water, which is 1.86 °C kg/mol.
Step 4: Use this value when calculating how much the freezing point of water will drop when a certain amount of solute is added.
