Find the pH factor of Water. Is this substance acidic or basic? Why?
Using this pH, show how to find the hydrogen ion content of the substance using the formula. Round to 10 decimal places or write your answer using scientific notation. Include units on your answer.

Water is neutral because [H+] = [OH-] = 1.00 x 10^-7 M
pH = - log [H+] = - log 1.00 x 10^-7 = 7
[H+] = 10^-pH = 10 ^ - 7 = 1.0 x 10^-7 M
The pH of water is supposed to be 7.0 but it can be EITHER acidic or basic.
Assuming that this is clean, pure water, the pH is 7.0, and to find the Hydrogen ion content you use this formula, derived from the find-the-pH forumula.
pH = - log [H]
[H] is the molarity of the Hydrogen ions
To find the concentration (or [H]):
antilog [-pH] = [H]
(* from the pH = -log[H] formula, you divide both sides by negative one.
-pH = log[H]
To get rid of the log on the right side, you need to take the antilog of both sides:
antilog [-pH] = [H])
or 10^(-7) moles/liter
