Theory about partial molar volume (PMV) can be found extensively on Chemistry and Chemical Engineering books as well as on web. Here are some key points that have to be noticed:
1. Molar volume (MV) and PMV: what is the difference?
2. Mathematical representative of PMV: what does it mean?
In the present experiment, we have to deal with an aqueous solution of sodium chloride (NaCl) and potassium chloride (KCl).
PMV can be calculated using the following equation:
What does it mean by this equation? Let consider a binary mixture of m mol component A in 1 kg solvent B. The volume V of the mixture can be expressed as a series of molality m of A as follow:
