The reason that a carbonated beverage may help settle an upset stomach is 
related to the carbonation rather than to its acidity.  The carbonation in 
the soft drink is carbon dioxide, which reacts with the acid in the stomach 
and helps "neutralize" it.  The carbon dioxide also facilitates belching, 
which also helps relieve some of the acid in the stomach.
