What series of procedures should be followed to obtain a pure, dry sample of hydrated copper(II) sulfate, $\text{CuSO}_4\cdot5\text{H}_2\text{O}$, from a mixture containing hydrated copper(II) sulfate and calcium carbonate, $\text{CaCO}_3$?
- Adissolve in water $\rightarrow$ distillation $\rightarrow$ crystallisation
- Bdissolve in water $\rightarrow$ filtration $\rightarrow$ crystallisation
- Cdistillation $\rightarrow$ crystallisation $\rightarrow$ heating to remove all water
- Dfractional distillation $\rightarrow$ filtration $\rightarrow$ heating to remove all water
