Br2 half reaction
WebFollow You have to separate the equation into half reactions first. NaBr → Br2 and Cl2 → NaCl Then you must balance all the elements that aren’t O or H. 2 Na+ + 2 Br- → Br2 + 2Na+ and 2 Na+ + Cl2 → 2 Na+ + 2 Cl- Next, add electrons to balance charge. 2Br- is being oxidized to Br2 and Cl2 is being reduced to 2 Cl-. WebTo balance a redox equation using the half-reaction method, the equation is first divided into two half-reactions, one representing oxidation and one representing reduction.The …
