1. Purpose
To measure partial molar volume through volume and density measurement experiments
2. Background Information
The partial molar volume of a substance J at composition is defined as follows:
V_J= 〖(∂V/(∂n_J ))〗_(p,T,n^' )…(1)
Here n_J means the number of a substance J.
For mixtures A and B, the change in volume is described as follows:
< 중 략 >
4. Procedure
1) The volume of the container (pycnometer)
① Weigh the completely dried pycnometer
② Fill the pycnometer with distilled water (up to the neck) and place the lid on it.
③ Keep the bottle in the water circulated thermostat until the system reaches equilibrium condition.
④ Take out the pycnometer from the thermostat. Remove the outside water. Weigh it carefully.
2) Density of the simple mixture
① Prepare sodium chloride in various concentrations (1, 2, 4 wt % NaCl)
② Put those solutions into each pycnometer and repeat the measuring process.
