The typical volume of an Escherichia coli cell is 1.0 m 3 . At pH 7 how many hydrogen ions are inside the cell?

The typical volume of an Escherichia coli cell is 1.0 μm 3 . At pH 7 how many hydrogen ions are inside the cell? A bacteria cell typically contains 1000s of macromolecules, many with multiple acidic and basic sites. What does your calculation of the number hydrogen ions in a cell tell you about the common notion that ionizable groups are surrounded with many H+ and OH- ions?
