A solution has a hydronium-ion concentration of 1.0 x 10-4 mol per liter. What is the pH of this solution? Is this solution acidic or basic? What is the hydroxide-ion concentration of this solution?
pH is a measure of the concentration of the hydronium ions present in the solution. To solve for the pH of a particular solution, we can use:
`pH = -log[Acid] = -log[H^+]`
`pH = -log (1.0x10^(-4)) = 4`

The solution is acidic.
Reason pH is less than 7.
The ionic product of a solution = [H+] X [OH-] = 1 x 10^-14
=> 1 x 10^-4 X [OH-] = 1 x 10^-14
=> [OH-] = 1 x 10^-10
