Question

An acidic solution of pH 5 has TIMES as many hydrogen ions (H+) as does a solution of pH 6.

Answer 1

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.
