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.

Titration is an essential technique used in many areas of chemistry to determine the concentration of a solution. In this practical experiment, the aim is to determine the value of x in Fe(NH4)2(SO4)2.xH2O using titration against a standard solution of potassium manganate (VII). The obtained results are used to calculate the amount of water of crystallization in the salt. This blog post provides an overview of titration and its importance in chemistry, as well as a step-by-step procedure and calculations for the Fe(NH4)2(SO4)2.xH2O experiment.

Titration – Precipitation

Titration – Precipitation

This experiment involves the determination of the number of water molecules of crystallization in hydrated barium chloride using titration and precipitation techniques with silver nitrate and potassium chromate. The procedure involves the reaction of chloride ions with silver ions to form a red precipitate of silver chromate, which indicates the end-point of the reaction. Barium ions also react with chromate ions, and to remove them, sulphate ions are added. The mass of anhydrous barium chloride and water present in the sample is calculated, and the ratio of BaCl2 to H2O is determined to find the value of x in the formula BaCl2•xH20. This experiment provides a great opportunity to understand the principles of titration and precipitation methods used to calculate the water of crystallization in compounds.

Titration is a fundamental laboratory technique used to determine the concentration of a substance in a solution. In this article, we will walk you through the steps of performing a simple acid-base titration using sodium hydroxide and hydrochloric acid. We will also discuss important safety precautions to keep in mind, such as wearing appropriate protective gear, handling chemicals with care, and disposing of waste properly. Additionally, we will address environmental concerns related to titration, including the safe disposal of chemical waste and glassware. By following these guidelines, you can perform a titration safely and responsibly while protecting yourself and the environment.

Titration – Redox Iron tablet

Titration – Redox Iron tablet

In this experiment, we explore the use of redox titration to determine the percentage by mass of iron (II) sulfate in iron tablets. By using potassium manganate in acidic solution, we can observe the permanent pink colour that indicates the end-point of the titration. With careful measurements and calculations, we can calculate the amount of iron (II) ions in the tablets and compare it with the information from the supplier. This experiment demonstrates the application of titration in analyzing the composition of drugs and supplements.
