- log(1 X 10 -9 M H3O)

= 9 pH

======So, obviously not enough hydronium to be acidic, so a basic solution.

-log(3.4 X 10^-5 M)

= 4.4685

14 - 4.4685

= 9.5 pH

What is the pH neutral solution?

When a pH level is 7.0, it is defined as 'neutral' at 25°C because at this pH the concentration of H3O+ equals the concentration of OH− in pure water. - Wikipedia


OH- of a solution which has a pH equals 10.95?

pH + pOH = 14. So pOH = 14 - 10.95 = 3.05 pOH = -log[OH-] [OH-] = 8.91 x 10-4 M

What pH values indicates a solution with the highest concentration of hydrogen ions pH equals 1 or pH equals 2 or Ph equals 7or pH equals 14?

pH = 14 is basic pH = 7 is neutral pH - 1 and 2 are acidic; pH = 1 is more acidic than pH = 2 Therefore a solution at pH 1 has higher concentration of H+ than at pH 14


What is the pH of a solution with a oh of 3.31 00000000 M?

[OH-] = 3.31 log[OH-] = pOH = .51982 14-pOH = pH = 13.48


What limits the pH of the solution?

The concentration of H+ or OH-.


Which solutions has a greater concentration of hydroxide ions a solution of pH 3 or a solution of pH 9?

The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.
