    💁‍♀️ HI I'M MELISSA MARIBEL

      @gortiz9267 3 роки тому

      I got the same result. If you have the pH already, to find pOH just substract the pH=8.5 to 14 (pOH = 14 - 8.5 = 5.5). Once you found pOH= 5.5, you can find OH. To find OH use this formula [OH-]= 10 ^- pOH.
      [OH] = 10^-5.5 = 3 x 10^- 9 or 3.1 x10^-9. The sig fig will depend on your professor really.
