$100 Question from H4 How does increasing the Concentration of a non-volatile Solute in water affect the following Properties? (a)Vapor pressure (b) Freezing point
$100 Answer from H4 (a)Decreases (b) Depresses freezing point
$200 Question from H4 Consider two solutions, one formed By adding 10 g of glucose (C6H12O6) To 1 L of water and the other formed By adding 10 g of sucrose (C12H22O11) To 1 L water. Are the vapor pressures Over the two solutions the same?
$200 Answer from H4 No. Would have a different mol Value and therefore a different Molality affecting Fp and Bp.
$300 Question from H4 Why does a 0.10 m aqueous solution Of NaCl have a higher boiling point Than a 0.10 m aqueous solution of C6H12O6?
$300 Answer from H4 NaCl actually has 2 moles of ions Per mole of NaCl
$400 Question from H4 Arrange the following aqueous Solutions, each with 10% by mass of Solute, in order of increasing Bp. (a)Glucose (b) Sucrose (c ) sodium nitrate
