From the procedure 1. Using a clean 5 mL pipet (inspect for cracks or dried chemical residue), measure out a small volume of acetic acid (not the entire 5 mL) and, holding the pipet horizontally, rotate the pipet to rinse it with the acid solution. Do not allow the acetic acid to flow into the pipet bulb. Dispense the liquid into a waste beaker. Repeat this procedure once. This will ensure the pipet is rinsed with the solution and no dilution will occur due to residual water. This will also serve as practice using the pump or bulb. 2. Carefully measure 5.00 mL of vinegar and carefully transfer the sample of vinegar into one of the Erlenmeyer flasks. 3. Using the DI water wash bottle and a graduated cylinder, add a total of ~20 mL of DI water to the flask. 4. Add 4-5 drops of phenolphthalein to the flask. Performing the Titration of Vinegar Report your measurements to the correct number of significant figures. From the procedure 1. Record the exact concentration of sodium hydroxide and the volume of the vinegar solution (5.00 mL) on the report sheet. The concentration of the NaOH solution is 0.099 M. Enter the exact concentration of the NaOH solution used (M) PREVIOUS ENTRY NEXT
