Healthy pH value of drinking water
A pH value of 7 means a substance is neutral. The lower value indicates acidity, and a higher value is a sign of alkalinity.
To better understand the range in pH, take a look at these examples: apple juice 3, orange juice 3.5, coffee 5.5, milk 6.2, baking soda 8.5, soapy water 10, bleach 12.
