We will assume complete dissociation.
Since we have the molarity of OH solution, we can calculate the p (OH) as follows:
p (OH) = - log (molarity of OH) = - log (7.5*10-3) = 2.1249
It is known that: p (H) + p (OH) = 14
Therefore, p (H) can be calculated as follows:
p (H) = 14 - p (OH) = 14 - 2.1249 = 11.875
