Density calculation problems for mixed solutions of various solids dissolved together
Thread Content
Suppose there are three salts (without crystalline water) with molecular weights of ABC respectively, and it is necessary to prepare 1 L of a 2 mol/L mixed solution. How can the density of this mixed solution be calculated?
Why not measure the density? The density dependence of multi-component mixed solutions is not very strict; they exhibit partial molar variation properties, and there are no on-the-spot calculation methods available. One may need to look up relevant information or even conduct experiments oneself, especially for mixtures like ABC.
Agree with the second floor; the current measurements are more accurate. Moreover, you haven’t specified the molar fractions of these three salts; even if the volume remains unchanged after the salts dissolve, it’s still impossible to do the calculation
I want to know if there is no such theoretical calculation method? Assume that the concentration of all three salt solutions is 3 mol/L
