A 375-gallon tank is filled with water containing 167grams of bromine in the form of Br- ions. How many liters of Cl2 gas at 1.00 atm and 20C will be required to oxidize all the bromide to molecular bromine?

DrBob222 · Answer

2Br^- + Cl2 ==> Br2 + 2Cl^- mols Br^- 167/atomic mass Br. Convert mols Br to mols Cl2. Use PV = nRT an solve for V in L.
