Discovering Photosynthesis: Testing a Leaf for Starch – A Hands-On Practical Experiment

Dive into the captivating world of plant biology with our hands-on practical experiment, designed to demonstrate the process of photosynthesis by testing a leaf for starch. By examining starch production in leaves, we can explore the incredible process through which plants convert sunlight into energy, producing the oxygen we breathe and the food we eat. This experiment offers an interactive and engaging way to learn about photosynthesis and develop a deeper appreciation for the crucial role plants play in sustaining life on our planet. Follow our detailed step-by-step guide and immerse yourself in the wonders of plant biology.

Titration – Exam Practice

Titration – Exam Practice

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.

Simple Titration – Acid/Base

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: 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.
