Detailed explanation-1: -Any solution that has a pH of less than 7 is considered acidic, and anything above a pH of 7 is basic.
Detailed explanation-2: -pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic.
Detailed explanation-3: -Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. pH scale, ranging from 0 (very acidic) to 14 (very basic/alkaline) and listing the pH values of common substances.
Detailed explanation-4: -As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral-neither acidic or basic.
