The student must have made an error in her measurement in the concentration of hydrogen ion in the basic solution given. From her measurement, the concentration is 1 × 10−3 M. If we calculate the pH, we get:
pH = -log ( 1 × 10−3) = 3
A pH of 3 does not signifies a basic solution it is in the acidic range. So, the measurement is wrong.
