Acid-base titrations. The most common type of titration is the acid-base titration. In this experiment, you will be using pH electrodes connected to the MicroLab Interface. Immediately prior to use, the electrodes are rinsed with deionized water and gently blotted with a tissue, then placed in the test solution. Using the values above, if titration requires 1.02 mmol of NaOH to reach the endpoint, the sample must also contain 1.02 mmol of acetic acid. For example, the titration of 16.00 mL of 0.184 M HCl requires 25.00 mL of a NaOH solution. The delivery of the titrant is adjusted with the stopcock on the buret. With practice, one can dispense fractions of a drop of titrant and control the procedure well enough that replicated titrations agree within 0.10 mL. Terms you will need to be familiar with in order to understand a discussion of titration are: Solubility equilibria. A titration is an experiment where a volume of a solution of known concentration is added to a volume of another solution in order to determine its concentration.

Repeat this procedure 1–2 more times to ensure that the graduated cylinder is conditioned. Many laboratories analyze consumer products to determine accuracy in the labeling of the product. At this point, the pH should change more than 0.3 pH units per addition, signaling the titration endpoint. The calibration standards for the pH electrode will be a pH = 4.00 (red) buffer solution, a pH = 7.00 (yellow) buffer solution, and a pH = 10.00 (blue) buffer solution. pH electrodes have a thin glass bulb at the tip. Record the exact concentration from the bottle of NaOH in Data Table A1. View the graph generated by the MicroLab titration program to become familiar with the appearance of a typical titration curve. As sodium hydroxide, NaOH, is incrementally added to the acid solution, some of the hydrogen ions will be neutralized. eBook includes PDF, ePub and Kindle version.

Remember to read the buret to the nearest. There are 1000 mmol in 1 mol and 1000 mL in 1 liter. Reading a buret to this accuracy is tricky; the last significant figure is expected to be an estimate. The most accurate answers come from averaging multiple attempts. A titration is a procedure in which two solutions are introduced to form a reaction that once completed, reaches an identifiable endpoint (Murphy, 2012, p.305).
