School Lab
This lab explores the process of acid-base titration, a fundamental technique in chemistry used to determine the concentration of an unknown solution. In this experiment, students will titrate a solution of hydrochloric acid (HCl) with a standard sodium hydroxide (NaOH) solution. By carefully adding the base to the acid using a burette and observing the color change of the phenolphthalein indicator, students will determine the point of neutralization, known as the equivalence point. This hands-on activity reinforces concepts such as molarity, stoichiometry, and the pH scale, while also providing valuable experience with laboratory equipment and techniques. Through the analysis of their results, students will gain a deeper understanding of chemical reactions between acids and bases and the quantitative relationships involved.
