Titration+of+Vinegar+-+Special+Instructions+&+Disposal


 * Special Instructions**
 * Position the computer so that it will not get wet if the buret spills
 * The pH probe will be useless if it is allowed to dry out. Leave the probe in the electrolyte solution until ready to use and immediately replace when done.
 * Rinse off the pH probe with de-ionized water before and after use.
 * Replace the pH probe into the electrolyte solution and store in an upright position. If the electrolyte solution does not completely cover the glass bulb at the end of the pH probe, tell your instructor before storing the probe.


 * Disposal Instructions**
 * Excess vinegar can be flushed down the drain or combined with excess NaOH to neutralize.
 * Excess NaOH can be neutralized by combining with 3.0M HCl. Add the HCl to the NaOH until pH paper indicates a pH of between 5-9. The solution can then be discarded down the drain. (Flinn Method #10)
