The flask contains 25 mL of an unknown diprotic acid aqueous solution that reacts in a 1:2 stochiometric ratio with NaOH. Titrate the solution with NaOH to determine the concentration of the acid. Perform a titration by setting the concentration of the NaOH solution and adding it to the acid solution using the different Add Base buttons. The equilvalence point of the titration is passed when the indicator color changes. The unknown sample can be titrated multiple times by pressing the Retitrate button and starting over. Enter the concentration of the unknown acid solution. To obtain accurate results, follow the following procedure: • switch the indicator to phenolphthalein titrate 1 mL at a time until solution turns pink, make note of volume added ⚫retitrate • add 1 mL at a time until 1 mL less than the first titration • add 0.05 mL at a time until the solution just turns pink x M
