The pH of a solution can be calculated using the formula: pH = -log[OH-]. Therefore, for a solution with [OH-] concentration of 10-12 M, the pH would be 12.
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
The pH of a solution can be calculated using the formula pH = -log[H+]. Substituting the given value of [H+] = 7.0 x 10^-12 into the formula gives pH = -log(7.0 x 10^-12) ≈ 11.2. Therefore, the pH of the solution is approximately 11.2.
The pH of a solution with a hydrogen ion concentration of 10^-12 M is 12. pH is calculated as -log[H+], where [H+] is the concentration of hydrogen ions in moles per liter. A hydrogen ion concentration of 10^-12 M corresponds to a pH of 12.

The pH of a solution with a hydrogen ion concentration of 1.0 x 10^-7 M is 7.0. This is considered neutral on the pH scale.
100 times. (10^2)
- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
Since pH is a logarithmic scale, each increase (or decrease) by 1 means 10 times, so the change of pH in a solution from 10 to 11 would be 10 times, 11 to 12 would be 10 times, and 12 to 13 would be 10 times, and (10)(10)(10) is 1000, so a solution with pH 13 is 1000 times more basic then a solution with pH 10
The pH of a solution with an H+ concentration of 7.0 x 10^-12 is 11.15. This is calculated by taking the negative logarithm (to base 10) of the H+ concentration.
