An acidic solution of pH 5 has<br> TIMES as many hydrogen ions (H+) as does a solution of pH 6.
Artyom0805 [142]

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+ = 10^{-5} (for pH = 5)    

=> pH = -log(H+)  

=> 6 = -log (H+)  

=> H+ = 10^{-6}  (for pH = 6)  

Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.
