the pH of a solution is defined as a measure of its hydrogen ion concentration. which of the following correctly defines the relationship between the pH and the hydrogen ion concentration of a solution:
a. when the pH of a solution changes by a factor of 2, the hydrogen ion concentration changes by 0.3
b. when the pH of a solution changes by a factor of 0.6, the hydrogen ion concentration changes by 3
c. when the pH of a solution changes by a factor of 0.3, the hydrogen ion concentration changes by 2
d. changing the ph of a elution does not affect the hydrogen ion concentration in any predictable way
e. when the pH of a solution changes by a factor of 3, the hydrogen ion concentration changes by 0.6
