Question

6. After determining the exact concentration of the NaOH you obtain an unknown acid. You work hard to collect the following data for this second set of titrations where you measure out an exact amount of acid and titrate with the (now known concentration) NaOH: | | Trial 1 | Trial 2 | Trial 3 | | :--- | :--- | :--- | :--- | | Volume of Acid (mL) | 5.00 | 5.00 | 5.00 | | Final buret volume (mL) | 34.53 | 25.98 | 43.46 | | Initial buret volume (mL) | 16.60 | 8.16 | 25.61 | 7. Calculate the volume of base used for each trial and the molarity of the Acid you used. | | Trial 1 | Trial 2 | Trial 3 | | :--- | :--- | :--- | :--- | | Volume of Base Used (mL) | | | | | Molarity of Acid (mol/L) | | | | 8. Calculate the average and the standard deviation of the three trials: Average Molarity = Standard deviation=
