Why CO2 is used in cold drinks?
carbonation, addition of carbon dioxide gas to a beverage, imparting sparkle and a tangy taste and preventing spoilage. The liquid is chilled and cascaded down in an enclosure containing carbon dioxide (either as dry ice or a liquid) under pressure. Increasing pressure and lowering temperature maximize gas absorption.

Which acid causes oil and butter rancid?
The peculiar smell and taste of rancid butter is generally assumed to be due to the presence of free butyric acid . . . . either it arises from butyric fermentation at the expense of the lactose or glyc- erol or else is the product of chemical changes and is set free from cer- tain glycerides in the butter.
