Now, what about basic solutions? Well, a solution is said to be basic if the concentration of the hydrogen ion is less than the concentration of the hydro hydroxide ion. And so in this case, the solution is said to be basic. Now, by the same exact reasoning, let's suppose that our hydrogen concentration is 1.0 times ten to negative eight. Let's find what the PH is of this particular solution. So once again we apply the same exact equation, equation A.
