Ripper math advice needed
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!).

Ripper math advice needed
Ric,
Titrettes are a somewhat expensive alternative; they are a reverse ripper. They have all of the same drawbacks as the ripper method though. I don't do the ripper either, more due to laziness than anything else... Ric wrote: Anyone have any advice / shortcuts on using Ripper method for determining free SO2?

Ditto that - one concern I've heard / read; the titrettes are not altogether
accurate. True / false? "Joe Sallustio" wrote in message oups.com... Ric, Titrettes are a somewhat expensive alternative; they are a reverse ripper.

True with reds, because they emulate the Ripper method. The problem
lies there. There should be some posts on this in the archives... Joe wrote: Ditto that - one concern I've heard / read; the titrettes are not altogether accurate. True / false?
