Water, in its purest form, has a pH of 7, which is in the middle of the pH scale. Particles in the water can change the water’s pH. Most water that is ready for use has a pH between 6.5 and 8.5.
pH is a chemistry measurement of the concentration of hydrogen ions in a liquid. A higher pH indicates fewer hydrogen ions.
A pH scale ranges in value from 1 to 14. It is used to measure the acidity or alkalinity of the liquid. Pure distilled water has a pH of 7. Anything below that is an acid and anything above 7 is an alkaline.
For example, vinegar is an acid with a pH of 2. On the other hand, bleach is an alkaline with a pH of 13.5.
This scale only applies to water-based liquids.
The pH of water may depend on if there are certain elements in it, such as metals, and minerals that are more or less available to the body. Heavy metals in water that has a lower pH will be more toxic because they are more available to the body. A high pH would make heavy metals less available and as such will be less toxic.
The pH level of the water may also be a sign that there are contaminants or bacterial life in the liquid. In general, a very high or low pH can make water unusable for certain things. For example, hard water contains lots of minerals. These minerals make the water alkaline.
On the other hand, water that has a low pH can corrode metal pipes and extract metal ions into the water, which would make it harmful to drink or use in the home.
Most of the time, water that is intended for drinking will be closer to a neutral pH. The Environmental Protection Agency (EPA) recommends the pH be between 6.5 and 8.5 for drinking water.
Drinking water and water-based drinks of varying pH levels may play a part in different health factors.
Alkaline water and alkaline products have been gaining popularity among members of the health community. According to alkaline water advocates, acidic environments in the body create multiple chronic conditions, which they claim could not persist in an alkaline environment.
They believe that drinking alkaline water helps the body to become more alkaline and treating a number of illnesses including cancer.
