A lower pH level indicates that a substance is more acidic. The reason Coca-Cola is more acidic than lemonade is because the carbonic acid, the stuff that makes cola fizzy, is stronger in acidity and greater in quantity in cola than the citric acid in lemonade. Because of this, flat soda is much less acidic.
less than PH 4
2.5 is the pH level of lemonade.
Lemonade is acidic and would have a pH in the 4.0 - 6.5 range.
A pH of 7 is neutral A pH of less than 7 is acidic and a pH greater than 7 is basic.
An acid pH is anything less than 7 including zero.

Acids have a pH level of less than 7.
The definition of acidic is having a pH less than 7.
Anything with a pH less than 7 is an acid. Anything with a pH greater than 7 is a base. pH = 7 is neutral
Acids are less than pH 7
