What is Electrolysis?
Electrolysis is the process of using electrical energy to split compounds and extract metals. When you pass electricity through an ionic substance, it causes chemical changes that wouldn't happen naturally.
The setup for electrolysis includes several key components working together. You need a battery as a power source, connecting wires, a pair of electrodes (the anode and cathode), and an electrolyte contained in a beaker.
Remember this! The word "electrolysis" comes from "electro" (electricity) and "lysis" (breaking down) - literally using electricity to break something apart!
Each component plays a specific role in the process. The positive electrode is called the anode, while the negative electrode is the cathode. These electrodes conduct the electrical current through the substance being broken down.
Electrolysis Equipment
To perform electrolysis, you'll need several essential pieces of equipment. First, a beaker holds the electrolyte, which is an ionic substance either melted or dissolved in water. The electrolyte is crucial because it contains free-moving ions that can conduct electricity.
The electrodes are solid conductors typically made of metal or carbon. They're placed in the electrolyte and connected to a power supply. The electrode on the left side is negative and called the cathode, while the one on the right is positive and called the anode.
Connecting wires allow electrons to flow through the circuit. The power supply (usually a battery) provides the electrical energy needed to drive the whole process.
Quick tip: Think of the electrodes as "doors" - the cathode is where positive ions enter the circuit, and the anode is where negative ions enter.
The Electrolysis Process
When you switch on the power, the battery sends electricity through the electrolyte, causing an amazing reaction. The electric current creates a separation between positive and negative ions in the solution.
The negative ions are attracted to the positive anode. When they reach it, they're discharged, meaning they lose electrons and become neutral atoms. This is where oxidation happens - electrons are lost at the anode.
Meanwhile, the positive ions are drawn to the negative cathode. Upon arrival, they gain electrons and are also discharged into neutral atoms. This is reduction - electrons are gained at the cathode.
Make this stick: Remember "ANODE" and "OXIDATION" both start with vowels, while "CATHODE" and "REDUCTION" both start with consonants. This helps you remember where oxidation and reduction happen!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didnโt even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as Iโm sure you too will see developments.
