7.3 to 7.4
Ph 4 and under and/or pH 8 and over -because Ph7 is the normal Ph level that humans should only take.
The pH level for most humans is around 7.4, which is slightly alkaline. The body tightly regulates pH levels to maintain homeostasis and proper function of organs and systems. Any significant deviations from this range can be harmful to health.
The best pH level for soap the use on an infant is 7. A safe level for humans pH level of soap is anywhere from 7 to 14. This is to mainttain a safe pH level in the skin naturally.
I would assume 7. It is the safest level of pH for humans 0 is battery acid and 14 is chlorine. 7 is water.
A pH level of 14 is extremely basic and can be dangerous. It can cause severe skin and eye irritation, chemical burns, and damage to tissues. It is important to avoid contact with substances that have a pH level of 14.
The pH level of stomach acid is typically between 1.5 to 3.5. It is highly acidic in order to break down food and kill bacteria in the stomach.
The highest pH level that humans can handle is around 11-12. Levels higher than this can cause chemical burns, skin irritation, and damage to tissues. Personal protective equipment should always be used when handling substances with extreme pH levels.
the pH level is 1.1
A pH level below 6.0 or above 8.0 can be dangerous for most living organisms, including humans. It can lead to chemical imbalances in the body, affecting various physiological processes. Maintaining a pH level close to neutral (around 7.0) is important for overall health.
A substance with a pH level of 3 would be considered acidic. Examples of substances with a pH of 3 include vinegar and orange juice.
