You determine the concentration of a solution of HCl by titration with NaOH. The titration reaction is: HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq) Using a volumetric pipet, you transfer 10.00 mL of the HCl solution into an Erlenmeyer flask, then dilute it with ~50 mL of water and add 3 drops of phenolphthalein. The endpoint is reached after you have added 44.00 mL of 0.1250 M NaOH solution from a buret. Calculate the molarity of the original HCl solution....

Ion chromatography - Anions lab Transfrer quantitatively the weighed portion of NaCl to the 100-ml volumetric flask. The flask need not be dry but must have been rinsed with de-ionied water as described above. why? Transfer approximatrly 1.5 times the volume of ACPS that you will need to a small beaker that will be supplied by instructor. This beaker will already have been rinsed with ACPS. Why should you not put your pipet directly into the bottle of ACPS solution...

You wish to prepare 100 mL of 0.750 M HCl from concentrated HCl (11.65 M). You are provided with a 100 mL volumetric flask and a 10 mL graduated pipet with 0.00 line at the top and calibration lines each 0.1 mL. When filled to the 0.00 mL line this pipet would dispense 10.00 mL of solution when drained leaving only the final inside drop. At what volume reading on the pipet should you start dispensing the 11.65 M HCl...
