Question: What are some easy tests I can do to
prove the chemical I have is Cobalt Chloride?

Hi Claire
Cobalt chloride exists in  different forms: anhydrous
and hydrated ,with 2,4, 6 water molecules.

CoCl2 (blue) + 6 H2O �¨ [Co(H2O)6]Cl2 (pink)

So if you have a sample that dry is blue and humid
or in solution turns pink you have most probably
the cobalt II chloride.
Thanks to ask NEWTON
