Ph 4 and under and/or pH 8 and over -because Ph7 is the normal Ph level that humans should only take.
A pH of 4
The normal pH of blood is 7,35-7,45.
No, adding salt to water does not change its pH level to become more alkaline. Salt does not directly affect the pH level of water.
Yes, using a hot tub with a high pH level can be dangerous as it can lead to skin and eye irritation. It can also cause the water to become cloudy and scale buildup on the hot tub surfaces, affecting its functionality. Regular monitoring and adjusting of pH levels is important for a safe and enjoyable hot tub experience.
When the pH level of a substance drops down to 2.5, at that point, the substance is considered to be dangerous. When the pH level of a substance drops down to 2.5, at that point, the substance is considered to be dangerous.
an extreme at either end of the pH scale is dangerous, but generally between 5.5-8.5 is safe, but really dont go pushing it
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.
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.
Yes. when the pH level is too high then the enzymes will denature and become inactive. :)
the pH of normal rain is said to be between 5.5 an 5. the pH is not 7 because carbonic acid is contained withing rain droplets from the atmosphere. this is how the atmosphere rids itself of toxins. pH of rain can also become very low when large amount of acid are present (from pollutants) the pH at which fish die in ponds when affected by acid rain is 4.9.

6.5 pH is too low pH for the blood. It is dangerous. You have got acidosis. The physician will take prompt action. The same pH in the stomach is too high. It is not dangerous. But it may hamper proper digestion of the food.
No, adding sea salt to water does not change its pH level to become more alkaline. Sea salt is a neutral substance and does not significantly affect the pH of water.
