WebbSo we have the pH and our goal is to solve for the concentration of hydronium ions, and pH is equal to the negative log of the concentration of hydronium ions. So we can plug our pH right into this equation. So that would give us the pH which is 9.25 is equal to the negative log of the concentration of hydronium ions. WebbThe negative sign was used before the word log. If the concentation of the solution is 0.005 M then its pH is -log(0.005) = 2.3 which indicates an acidic solution.
