* Understanding pH: pH is a logarithmic scale that measures the acidity or alkalinity of a solution. Each whole number difference in pH represents a tenfold difference in acidity or alkalinity.
* Calculation:
* The difference in pH between 11 and 8 is 11 - 8 = 3
* Since each whole number difference represents a tenfold change, a pH of 11 is 10 x 10 x 10 = 1000 times more alkaline than a pH of 8.
Therefore, a substance with a pH of 11 is 1000 times more alkaline than a substance with a pH of 8.
