The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.
The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.
- The concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log(H+) then,
=> 5 = -log (H+)
=> H+ = (for pH = 5)
=> pH = -log(H+)
=> 6 = -log (H+)
=> H+ = (for pH = 6)
Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.
