Complete kit for raw and corrected volatile acidity determination with two Schilling burettes

A standard sodium solution is poured into the distillate obtained from steam distillation with some additional drops of phenolphthalein until it turns pink. In the presence of sulphurous acid (SO2) in wine, the value found above is slightly in excess. It can be easily corrected by running an iodometric standard solution on the sample which has just been neutralized.
