In this case, according to the given ionization of magnesium hydroxide, it is possible for us to set up the following reaction:
Thus, since the ionization occurs at an extent of 1/3, we can set up the following relationship:
Thus, x for this problem is:
Now, according to an ICE table, we have that:
Therefore, we can calculate the H^+, pH and pOH now:
