D) Calculate pH of the solution containing 0.012 M acetic acid in water considering the hydronium
generated ONLY from the acid. Where pH = -log[H3O+].
E) Most common pH meters can only read two decimal places. Based on this information, would you
for all practical purpose consider the hydronium concentration coming from water when
considering pH of a strong acid? Explain.
