In CuSO4+CoCl2=CuCl2+CoSO4

Are both CuCl2 and CoSO4 aqueous?

CuCl2 is also aqueous
Let me point out two things here.
First, solid USUALLY don't react so most reactions of this type react, if they react at all, because they are in aqueous solution and it's the ions that react.
Second, reactions occur because of a reason.
1. A precipitate is formed.
2. A gas is formed.
3. A slightly ionized substance is formed.
4. A redox (oxidation-reduction) rxn is taking place.
In the above equation none of these is present and there is no reaction. What you have going on is a mixing of the ions in solution.
