| The goal is
to get the precipitate between pH 8.5 and 10.78. After you get the precipitate, the
goal is to wash it well. Washing the precipitate will take the pH down closer to
8.5. The m-state is in the precipitate. You can take the pH down to 4 or 5 and the
washed precipitate will re-dissolve but the m-state will still be in the
liquid. |
