The log to the base 10 of the concentration of Hydrogen ions (H+) in a solution times -1.
pH = -log10[H+]
This measures the acidity of a solution. A low pH indicates a high concentration of H+(and therefore a low concentration of OH-) which is an acidic solution, and a high pH is found in alkaline solutions (low H+ and high OH-). Neutral is 7 - the pH of water, when there are the same number of H+ ions as OH- ions.
percent hydrogen 0-6 is acidic 7 is neutral 8-14 is basic measures amount of unbonded hydrogen ions
the acidity of a ceartin substance
Seta in biology is bristel or stiff hair.
A SolutionA Solutiona solution However: Mastering Biology by Pearson says that the answer is a BUFFER. Do NOT select "solution," as that is incorrect.

We all know that biology can be tough sometimes but you have to think of it as this way, as a biology teacher I think that all learners should try my method. The following answers your question. If you make the pH 5 then it ill be too low for the alkali or acid to reveal its colour but if you put it at 9 it is too high. So to be safe the pH always needs to be 6-8.
its got to do with science
A pH over 7 is basic.

Biology means it's about Trees and Plants,ect....
effect of ph and concentration of subtrate
It depends on how much you add, but when we did it in my CP Biology class we got 10.

Biology means the science of life or living organisms
forward or before. I think its the same for biology.
Biology is the study of living and non living organisms.
A pH of 5 is closer to an acid. 7 is neutral pH.
I do believe it is 7, but i cannot be entirely certain. This is coming from my biology teacher. Hope it helps :)
