So the PH is equal to negative log of the hydrogen I concentration and is equal to. So you plug that into the calculator and we get a value of eight. So we see that anytime this condition is true, the PH will always be above seven. In fact, anytime we have a solution with a PH of above seven and we are at room temperature, that means our solution will be a basic solution. So at room temperature, a PH of above seven means the solution is basic. So we have an acidic solution, is a solution in which the PH is below seven.
