Concept explainers
(a)
Interpretation:
The osmotic pressure in the atmosphere of an aqueous solution of 5.00 g of NaCl in 350.0 mL solution at 50°C needs to be determined.
Concept introduction:
Colligative properties are the properties that depend on the number of particles present in the solution. Elevation in boiling point, depression in freezing point, lowering in vapor pressure and osmotic pressure are some common examples of colligative properties. Vapor pressure is the pressure that is exerted by vapor on the liquid surface in a closed system when the system is in
(b)
Interpretation:
The osmotic pressure in the atmosphere of an aqueous solution of 6.33 g of sodium acetate in 55.0 mL solution at 0°C needs to be determined.
Concept introduction:
Colligative properties are the properties that depend on the number of particles present in the solution. Elevation in boiling point, depression in freezing point, lowering in vapor pressure and osmotic pressure are some common examples of colligative properties. Vapor pressure is the pressure that is exerted by vapor on the liquid surface in a closed system when the system is in thermodynamic equilibrium.
