R120 General Chemistry F2020 Name: Titration of an Unknown Acid: V, = 25.00 mL Initial Volume Concentration of Final Volume Volume of NaOH (V.) (mL) (V.) (mL) used (mL) V Unknown Acid (M) Flask 1 0.28 25.05 24.77 Flask 2 0.00 25.15 25.15 Flask 3 0.10 25.25 25.15 M Average Acid Concentration: % error: Note: Unknown acid is HCI, so 1 mol HCI gives 1 eq H* for an acid/base titration Given Value: 0.1985 M HCI Calculations: Na. OH caq) + HA caa) → NacI caq) t HzO (e) Average NaOH molayrky: .1410M Conclusion: 1. Where do you think errors could come from in the experiment? 2. How would you modify the experiment to improve % error?
