Place your solid components in water (this will be step one). The result will be that A will remain as a solid and will sink to the bottom of the solution. Pour off the water that remains containing B and C. Heat the water to evaporate it, and you will be left with a mixture of B and C in solid form. Next, place this resulting solid mixture in ethanol. Again, C will sink to the bottom, and B will remain in the liquid. Pour off the liquid, obtaining the pure solid C. Heat the ethanol containing only B, and when the liquid has evaporated you will be left with B. as a flow chart, this will be ABC - Add to water BC in water A remains solid Evaporate water, add BC to ethanol B in ethanol C remains solid Evaporate ethanol and obtain B Hope this helps!
