When the hydronium ion concentration equals 10 moles per liter, what is the pH of the solution? Is the solution acidic or basic?
A)pH = 0, this is an acidic solution.
B)pH = 1, this is an acidic solution.
C)pH = -0.301, this is an acidic solution.
D)pH = 7, this is a neutral solution.

The pH is calculated using the formula pH = -log[H3O+]. For a hydronium ion concentration of 10 moles per liter, pH = -log(10) = -1. Since the pH is negative, it indicates a highly acidic solution. However, the closest choice given is pH = -0.301, which is still acidic.
