I believe it stands for "plate historical"...
A pH over 7 is basic.
A pH of 5 is closer to an acid. 7 is neutral pH.
pH with one hydrogen?
A urine pH of 7.5 could mean several things. If the pH is constantly 7.5 it could mean that ones kidneys are producing ammonia to neutralize the toxins in the body.
@25'C ,pH higher than 7
Acidic: pH < 7 Basic : pH > 7
ph
Hydrogen
Don't you mean PH? PH: 6.5 to 7.5
it is neutral. Water is a 7 on the pH scale
The pH scale ranges from 0 to 14 such that something with a pH of 0 is extremely acidic and something with a pH of 14 is extremely basic. A neutral pH is in the middle and has a pH of 7. An example of something with a pH of 7 is rain water.
