In industry, lodine is produced from the NalO3 that remains after sodium nitrate has
been crystallised from the mineral Chile saltpetre.
The final stage involves the reaction between NalO3 and Nal in acidic solution.
Half equations for the redox process are given below.

Use these half-equations to deduce an overall ionic equation for the production of iodine
by this process.
a) Write the overall ionic equation:
