Copper Electroplating Lab Report | Faraday’s Laws & Redox Reactions Explained
Introduction Electroplating is an industrial process that uses electricity to coat the surface of a metal object with a thin layer of another metal. In copper electroplating, a copper anode and a conductive object (the cathode) are placed in a solution containing copper(II) ions. When an electric current is applied, …
Electrolysis Explained: Process, Examples & Applications
Introduction Have you ever looked at a piece of jewellery and wondered how it got that flawless gold coating? It is not paint, and it is definitely not done with a tiny brush. The secret lies in a process called electrolysis. Electrolysis is where electricity steps in and makes chemical …
Law of Definite Proportions: Discovery, History, Questions
Introduction – Law of Definite Proportions Why does water always behave like water, no matter where it comes from? Why do compounds like carbon dioxide and copper carbonate always form in the same way? Before scientists understood atoms, they were already noticing something strange but consistent. When elements combine to …
States of Matter – Solids, Liquids & Gases Explained(GCSE )
Introduction:States of Matter Everything around us air, water, metal, or even plastic is made of something called matter. But matter doesn’t always look or act the same way. Why? Because it can exist in different forms called “states.” This is one of the first big ideas you learn in chemistry: …
