A solution of 0.100 M HCI and a solution of 0.100 M NaOH are prepared. A 40.0 mL sample of one of the solutions is added to a beaker which is then titrated using the other solution. A pH electrode is used to obtain the data plotted in the titration curve shown here. a. Identify the solution that was initially added to the beaker. Explain your reasoning.
