3. Some of the reactions of halogens are shown below. They are all examples of redox reactions. In each case state which element is oxidised and which is reduced, and give the oxidation states before and after the reaction. It says it wants you to put the state numbers under each element etc.
a) 2AgCl = 2Ag + Cl2
b) Cl2 + 2OH- = Cl- + ClO- + H20
c) 2Fe + 3Cl2 = 2FeCl3
d) 3Br2 + 6OH- = BrO3- + 5Br- + 3H2O
e) 2Br- +2H+ + H2SO4 = Br2 + So2 + 2H2O
f) 8I- + 8H+ + H2SO4 - 4I2 + H2S + 4H20
g) 4IO3- = 3IO4- + I-
h) H2 + Cl2 = 2HCL
i) 2F2 + 2H2O = 4HF + O2
Please notice that you will have to look quite hard to see the minus signs!
Thanks for all your help, much appreciated! Please
