how much so2 Analysis pdf

The amount of molecular SO2 that is in a solution depends on both the concentration of free SO2 and the pH of the wine. In simple terms, it takes roughly 10 times as much free SO2 to inhibit microbial activity in a wine with a pH of 4.0 than is needed in a wine with a pH of 3.0.

    The Ripper method is another commonly used method for the analysis of both free and total sulfur dioxide in wine. In this method, standardized iodine is used to titrate free sulfur dioxide. The completion of this reaction is signaled by the blue-black color change produced by the starch indicator which results from the presence excess of iodine.
