How to Determine the Concentration of a Hydrochloric Acid Solution using Acid-Base Titration: An IGCSE Prescribed Practical

Acid-base titration is a widely used technique in chemistry to determine the concentration of an unknown acid or base solution. In this practical investigation, we will be using acid-base titration to determine the concentration of a hydrochloric acid solution. By reacting a known volume of the acid solution with a standard solution of a base, and using an indicator to determine the endpoint of the reaction, we can calculate the concentration of the unknown acid solution. This technique has important applications in many areas of chemistry, making it an essential part of any chemistry curriculum. In this blog post, we will explain the scientific principles behind acid-base titration, the equipment needed, step-by-step instructions, expected findings, and model calculations. We will also answer some common questions related to acid-base titration, including the purpose of using an indicator and how to calculate the concentration of an unknown solution. Whether you are a student or a chemistry enthusiast, this post will help you understand acid-base titration and its importance in the world of chemistry.

Thermometric titration is a powerful technique used to determine the concentration of acids and bases by measuring the temperature change during a chemical reaction. In this article, we explore the process of thermometric titration and how it is used to calculate the enthalpy change of neutralization for hydrochloric acid and ethanoic acid using a standard solution of sodium hydroxide. We outline the required materials, the titration procedure, and the calculation process involved. Additionally, we answer common questions about the enthalpy change of neutralization, the experimental results for hydrochloric acid, and the heats of neutralization for weak acids and bases.

Atomic Emission Spectra

Atomic Emission Spectra

The aim of the experiment is to introduce the spectra emitted by some s-block elements when their atoms are excited by heating in a Bunsen flame. The experiment requires a hand spectroscope, a Bunsen burner, flame-test wire, hydrochloric acid, and safety glasses. The procedure involves observing the difference between a continuous emission spectrum and a line spectrum by heating various elements and observing their emission spectra. The experiment also aims to identify the reason behind the production of a unique line spectrum for every element.
