Answer:
To calculate the [OH-] and the pH of a solution, we can use the relationship between [H3O+] (hydronium ion concentration), [OH-] (hydroxide ion concentration), and the pH scale.
1. The concentration of [H3O+] is given as 1 x 10^-4 M.
2. In a neutral solution, [H3O+] and [OH-] are equal. Therefore, the [OH-] concentration is also 1 x 10^-4 M.
3. To find the pH, we can use the equation: pH = -log[H3O+].
Plugging in the given [H3O+] concentration, we get:
pH = -log(1 x 10^-4)
Simplifying, we have: pH = 4.
So, the solution has a [OH-] concentration of 1 x 10^-4 M and a pH of 4.
