Does the ph of soda change when it goes flat
WebFeb 6, 2012 · This is the pH scale. The scale goes from 0 - 14. A pH of 7 is neutral, a pH of less than 7 is acidic, and a pH of greater than 7 is basic. ... What type of change occurs … WebFlat coke is less acidic than carbonated coke. I did a lab report on this topic, and found that Carbonated coke had a concentration of around 0.131M whereas flat coke had a concentration of 0.064M. I guess we can assume that the carbonic acid that's dissolved in Coke makes up a large proportion of the acidity.
