PH scale a vegetable with a pH of 5.3 would be?
A vegetable with a pH of 5.3 would be considered mildly acidic on the pH scale. The pH scale ranges from 0 (most acidic) to 14 (most basic/alkaline), with 7 being neutral. pH values below 7 indicate acidity, so a vegetable with a pH of 5.3 falls into this category.
