In the presence of an alkali, Cl2 reacts to form Cl- and ClO3- , as follows:
3 Cl2(g) + 6 OH−(aq) → 5 Cl−(aq) + ClO3−(aq) + 3 H2O(l)
a. Calculate the oxidation number for chlorine in each of the species.
b. Write a half equation for the formation of Cl- from Cl2
c. Write a half equation for the formation of ClO3- from Cl2
d. Name and explain what type of reaction this is.
e. Identify which species is being reduced
f. identify which is the oxidising agent
