pH is a function of the concentration of hydronium ions in a water solution and theoretically can take any number, not just the traditional 1-14 range. However there are physical limits to how much of this substance can be present in a solution without precipitating and this establishes the lower limit of pH. At the other end of the scale pH can be determined mathematically from the concentration of hydroxide ions, but this too is limited to a point, setting the upper limit for pH. These limits take the allowable pH range down to about -5 and up to perhaps 20.
a pH of 7 is neutral. anything below 7 is acidic, and everything above is basic.
Normal serum pH is slightly alkaline and ranges from 7.35-7.45
If the pH blood level persisted outside the its normal range then the enzymes in the body will not operate and may even die This will cause the organisms to become ill or to die
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.

The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
The range of pH values is 0 - 14.
High range pH refers to the measurement of pH values greater than 7.0, indicating alkaline or basic conditions. This can typically range from pH 8 to pH 14. High range pH is important in applications such as water treatment and regulation of soil pH for agriculture.
The pH range for carbonate-bicarbonate buffer is 9,2.
A base typically has a pH range of 8 to 14. pH values above 7 indicate alkalinity, with higher values indicating stronger bases.
most fish live in a pH range of 5.5 to 7.5
The optimal pH range for yeast growth is typically between 4 and 6. Yeasts are able to tolerate a slightly broader pH range, from 3 to 8, but their growth is most efficient within the optimal range. pH outside of this range can affect yeast metabolism and growth rate.
the pH range is around 10
The pH range of an acid is typically below 7 on the pH scale. Strong acids have a pH closer to 0, while weak acids have a pH closer to 7.
The pH of the bloodstream is normally in the range of 7.35-7.45
These are two indicators:Methyl orange: pH of 3.1 (color red) to 4.4 (color yellow)Phenolphtalein: pH of 8.2 (colorless) to 10.0 (color purple)1 and 2 toghether: pH of 3.1 red to 4.4 yellow, staying yellow up till 8.2,then changing to greenish-purple from 8.2 at 10.0
The pH range of bicarbonate is typically between 8.3 and 10.6. Bicarbonate acts as a buffer in the blood to help maintain a stable pH level.
pepsin is activated from pepsinogen in stomach. the pH range for its optimal ativity is at acidic pH between 1.5 to 2. It is also stable upto pH8 and can be inactivated at basic pH from 8.5,
