This range is only a convention.
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,
