#### Question #a5e9d + Example - Socratic

2016/7/2· Explanation: Calcium metal, Ca, will react with bromine, Br2, to form calcium bromide, CaBr2, a white solid. This is a redox reaction in which calcium is being oxidized, its oxidation state going from 0 to +2, and bromine is being reduced, its oxidation state going from 0 to −1. Now, I think that this reaction actually involves gaseous bromine.
