An acid base volumetric titration
This YouTube video demonstrates the process of conducting a volumetric titration to determine the concentration of ethanoic acid in vinegar. The video shows step-by-step instructions on preparing a dilute vinegar sample, adding thymolphthalein indicator, and using a burette to add sodium hydroxide until a permanent blue colour change is achieved. The video explains how to calculate the concentration of ethanoic acid in the original undiluted vinegar using the titration formula. Volumetric titration techniques are highlighted as useful in quantitative chemical analysis, such as measuring acidity in drinks and analyzing the effects of acid rain on water samples.
