1. The problem statement, all variables and given/known data Graphite does not react with HCl as I saw in a previous lab. However, I looked at activity series on google and they all have carbon as more reactive than hydrogen, so theoretically graphite should react with HCl. However, this is not the case. 2. Relevant equations No equations. Just plain logic, common sense, and a bit of intuition. 3. The attempt at a solution I attempted to figure this out by googling all over, but I am still confused. Could anyone please help clarify why graphite and HCl do not react? Thanks!
