  Sec Sch Chapter 13 Redox

  The history of oxidation reduction reactions can be traced back to the early time of the human development, since the first time that the human knew the fire and used it in their daily life, especially the Copper‐Bronze age of the human development, the early time, around 4000–8000 years ago. The introductory course of redox helps students in later chapters such as metals and electrolysis. Redox provides insight into the study of redox reactions. It is a simple course to pick up but challenging to master, with the main challenge being the different methods used to identify if an element is oxidized or reduced. This course is designed to tackle the challenges of the course, with clear and succinct lectures focusing on oxidation states and redox agents and applying the concepts in exam style questions.

  Sec Sch Chapter 14 Metals

  The chapter on metals is a chapter that may seem simple at first but progressively becomes harder as more and more skills are being tied to the reactivity series of metals as well as the content-heavy topic on the blast furnace which is disliked by many students. This is why the course is highly recommended for students as it provides a wide variety of easy to understand lectures and tutorials for students to overcome the various difficulties in memorizing and applying the metal reactivity series as well as the various steps’ reactants and products of the blast furnace.

  Sec Sch Chapter 15 Electrolysis

  Electrolysis was first discovered in the year 1800. After the invention of the voltaic pile by Alessandro Volta the same year, chemists used a battery and placed the poles in a container of water. There they discovered that current flowed and that hydrogen and oxygen appeared at the electrodes. When it comes to the chapter on electrolysis it is quite a challenge for most students as many end up being confused by the various nuances of the chapter as well as surprised by the various uses of electricity in chemistry. This is further compounded by the added needs of using the reactivity series of metals for this chapter. Which is why this course will be needed by most students as it goes in depth with the various uses for electrolysis for both chemistry and everyday life. And in time, even a normal student like you can invent something as revolutionary as a battery.
