The smaller the number, the stronger the acid, the higher the number, the stronger the alkalinity. Test for water quality: low alkaline drinking water is good for your health. (PH=6.5-7) Cosmetic test: low acid cosmetics are more suitable for the skin. (PH=5-6.5) Detection of laundry detergent: Weak alkaline detergent can reduce hand damage. (PH=7-8) Body test: Through urine/saliva pH, you can judge whether the body is abnormal beforehand. ( urinary PH= 5.0-7.5, salivary PH= 6.6-7.5) Food analysis: the acid-base balance of the body can be maintained by pH from ingested food.
