7.4
Arterial Bloods pH is 7.38-7.42. pH is slightly higher because there is less carbonic acid (H2CO3).
The normal pH of a stream ranges between 6.5 to 8.5. A pH value that is higher or lower than this range would adversely affect the survival of the aquatic organisms living the stream.
The pH or normal rainfall is 6
It is important for the proteins and compounds within an organism to have a very narrow range pH. Any deviation will compromise their function. Since our diet can change the internal levels of acid and base there is a buffering system within the plasma and adaptations of both the pulmonary, renal system and digestive system to excrete excess base or acid to keep internal pH as close to 7.4 as possible.
7.35-7.45 in a normal adult
normal pH of sweat is between 4.3 to 4.7
Normal pH is between 7.35-7.45.
The normal pH range would be like 6.5 to 7.5, pretty much neutral most of the time
most fish live in a pH range of 5.5 to 7.5
7.0 is neutral.
The normal bllod pH in humans is 7.40 with a normal range of 7.35 to 7.45.
The pH value for normal human urine is about 6.6, acidic.
Normal serum pH is slightly alkaline and ranges from 7.35-7.45
7.35-7.45
Normal blood pH is around 7.4 A normal saliva pH range is somewhere between 6.0 to 7.4
Normal PH for arterial blood is 7.4 and it is basic ph below 7 is acidic and 7 to 7.3 is neutral
