WebJan 16, 2016 · 1. I was conducting a titration of a saturated C a ( O H) X 2 solution against H C l using a pH meter (the kind with a glass electrode). At the beginning of the titration, the pH reading would drop a bit every time I added a drop of H C l. However, near the equivalence point, when I added a drop of H C l, the pH reading would drop rapidly, but ...
WebACID-BASE TITRATION Link: You tube: Acid Base Titration (Vinegar Titration) SMARTERTEACHER ANALYSIS OF VINEGAR: Vinegar is a dilute solution of acetic acid. Law requires that vinegar should be at least 4% acetic acid by weight. Measure exactly 5ml of vinegar into an 250ml Erlenmeyer flask.
