The answer is A. 0 because 9 and 14 would be a pH of basic solutions because they are greater than 7; 0 and 6 are acidic because they are less than 7 but zero is smaller than 6 so it is the most acidic

The answer is 0. The pH scale ranges from 0 to 14. 0-6 being very acidic. 7 being neutral and 8-14 being very basic.
