SO we've got sodium thiosulphate and 10ml of potassium iodide (0.4M), with 1ml of starch mixed with 10ml of ammonium peroxdisulphate. Gave black/blue colour after a minute or so. Then the experiment was repeated but this time with copper sulphate. Colour formation occurred faster. I appreciate the copper ion is a homogenous catalyst but exactly what is happening to quicken the result PLEASE!!
