Microbial Cultures: Observing Growth on Agar Plates – IGCSE Prescribed Practical

In this practical investigation, we explore the world of microbiology and learn how to grow microbial cultures on agar plates while observing their growth characteristics. Discover the necessary equipment needed and learn the importance of aseptic technique to prevent contamination. Through the process of incubation and making subcultures, we uncover the unique colony characteristics of different microorganisms. By the end of this experiment, you'll gain a deeper understanding of microbial growth and the importance of laboratory safety.

Simple Titration – Acid/Base

Titration is a common laboratory technique used to determine the concentration of a substance in a solution. In this case, we will be performing a titration with sodium hydroxide (NaOH) and hydrochloric acid (HCl) to determine the concentration of HCl in a given solution.

Iron Tablet Titration: Step-by-Step Guide

Iron tablet titration is a common laboratory method used to determine the amount of iron present in a sample, such as an iron supplement tablet. This method involves reacting the iron in the tablet with a solution of potassium permanganate (KMnO4) to produce a purple colour. The endpoint of the titration is reached when the purple colour disappears, indicating that all of the iron in the tablet has reacted with the KMnO4.
