Neutralizing Hydrochloric Acid Experiment: Finding the Mass of Calcium Oxide Required

This video is a lecture presentation on the topic of neutralizing hydrochloric acid. The presenter explains the chemical reactions that occur and demonstrates an experiment to determine the mass of calcium oxide required to neutralize a particular volume of 1 molar hydrochloric acid. The experiment involves adding calcium oxide to hydrochloric acid in increments and measuring the pH with a pH meter after each addition. The data is then plotted on a graph to determine the mass of calcium oxide needed to neutralize the acid. Safety precautions are also discussed.
