Using the following information, you will predict the products of a redox reaction based on the following information:  F 2 , Co3+, Cl 2 , I 2 , and K+ are all oxidizing  agents (giving F-, Co2+, Cl-, I-, and K  respectively)               Best oxidizing agent    F2 > Co3+ > Br2 > I2 > K+   Worst oxidizing agent

Part 1: Starting with two test tubes, each containing water. You add a few crystals of CoF3 to one tube and a few crystals of KBr to the other. The crystals dissolve. Complete a balances equation for the dissociation of CoF3 into ions.

CoF3(s) Co3+(aq)  +   3F-(aq) water F is a stronger oxidizing agent = being reduced/loses electrons (becomes F-) Co is a stronger reducing agent= being oxidized/gains electrons (becomes Co3+)
