This instrumentation is used to calculate the amount of unknown acid by measuring the amount of base it takes to neutralize the acid. To know if the solution has been neutralize there are two major ways. The first uses a pH meter in the beaker. The second uses an indicator. With this we can infer that the second method is much more detailed than the second one, that’s maybe why the pH of an unknown weak acid wasn’t determined not until the second method.
