Got stuck on this in my revising!
An aqeous solution of bomine was added to an aqueous solution of chloride ions and also to an aquous solution of iodide ions.

State what you would see in each case, inlcude an equation for any chemical reaction that takes place, and explain the trend shown by these observations.

Thanks,
Harry
