What Is Acid-Base Balance? The acidity and alkalinity of your blood are measured using the pH scale. The pH scale ranges from 0 (very acidic) to 14 (very alkaline). Blood is usually between 7.35 ...

Acid and alkaline levels are measured on a pH scale. An increase in acidity causes pH levels to fall. An increase in alkaline causes pH levels to rise.

The pH scale, otherwise known as the acid-base scale, runs from 0 to 14. It measures how acidic a solution of a substance in water is. For example, pure water has a pH of 7.

Solutions can be acidic, alkaline or neutral. For example, pure water is neutral with a pH of 7. A solution of common salt (sodium chloride) is also neutral, so it has a pH of 7 too. In science we ...
