Answer:e. a solution with a pH of 9 is acidic
Explanation:
The pH scale shows the degree of acidity or alkalinity of a substance. The scale is graduated from 0-14. pH of 0-6.9 shows acidity, 7 is the midpoint of the scale and indicates neutrality. 8-14 shows alkalinity. An increase or decrease of pH by one digit indicates a ten fold increase or decrease in hydrogen ion concentration. From the foregoing, a pH of 9 can never indicate acidity.
