IGCSE Prescribed Practical: Making Salts from Metals and Acids

IGCSE Prescribed Practical: Making Salts from Metals and Acids

Making salts is an essential part of chemistry, and this practical investigation teaches students how to produce different types of salts using different metals and acids. In this blog, we'll explore the step-by-step methods for producing a pure, dry sample of a soluble and insoluble salt using filtration, evaporation, and crystallization techniques. We'll also discuss the differences between soluble and insoluble salts, as well as how to assess the purity of salt samples. By the end of this article, you'll have a greater understanding of the importance of salts in chemistry and how they are produced.

IGCSE Prescribed Practical: Identifying Metal Ions Using Flame Tests

Flame tests are a simple and effective method for identifying metal ions in solution based on their unique atomic emission spectra. This practical investigation involves heating metal salt solutions in a flame and observing the color produced to identify the metal ion present. By understanding the principles of flame tests, we can apply this technique to real-world applications in analytical chemistry and various industries. This blog post explores the step-by-step method for performing flame tests, as well as the expected findings and limitations of this technique. Additionally, we answer frequently asked questions to deepen our understanding of this IGCSE Prescribed Practical.

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.
