Problem- Okay so we have sodium podium tartrate and hydrogen peroxide reacting. The reaction is catalyze by cobalt (II) chloride - there are 4trials done: 50,60,70,80 degrees Celsius. Obviously we know that the cobalt 2 chloride is the catalyst as when we add it to solution, solution goes pink and then green, and then back to pink. How could we prove that cobalt 2 was actually the catalyst though? How could we prove using materials from a regular high school science room? Possibly titration?

I need proficient help to solve the above problem this is AP chem., not chem110
