Anyone have any advice / shortcuts on using Ripper method for determining free SO2? Been struggling with the procedure layed out by Margalit. It's terribly time consuming and full of opportunities for error - especially first titrating for the normality factor of the iodine solution before even titrating for the SO2.
Anyone have any shortcuts that are verifiable? Or alternative methods; short of aeration-oxidation (I'm not clever enough to build the appratus!).
Ditto that - one concern I've heard / read; the titrettes are not altogether accurate. True / false?
True with reds, because they emulate the Ripper method. The problem lies there. There should be some posts on this in the archives...
