Why won't SO2 wont show up?
How do you test for SO2 gas? Why would it show up if you're never taught how to test for it -_-
Ok looks like I was mistaken. I just confirmed the CIE amendment to the syllabus for P3.
It was the Pb2+ ion that they've removed not SO2. So, K2Cr2O7 will very much be on the reagents bench and you'll have to test for it by soaking the white strips of filter paper. If it turns from orange to green, voila.
