NCERT Solutions for Class 8 Science Chapter 14 – Ever wondered why electric currents can cause chemical reactions? It’s like magic – only it’s pure science! In Chapter 14, students learn about the electrifying world of chemical effects caused by electric current. It’s not just about switching on lights; it’s about how electricity can change things at the molecular level. Let’s break it down!
What Happens When Electric Current Passes Through a Conducting Solution?
When electric current flows through a conducting solution (like water mixed with salt), it can break down the chemicals. This process is called electrolysis. Imagine splitting water into hydrogen and oxygen – that’s what electrolysis can do! It’s like when your phone battery charges and stores energy, except in this case, we’re breaking things apart instead of building them up.
Electroplating: Making Objects Shine Like a Million Bucks 💎
Ever wondered how jewelry gets that shiny, metallic coating? Electroplating! By passing an electric current through a solution of metal salts, you can coat objects with a thin layer of metal. This is used to make things like coins, jewelry, and even parts of your favorite gadgets.
Corrosion: The Sneaky Villain!
Now, while electroplating is cool, there’s also a villain in the world of electricity: corrosion. It’s when metal reacts with moisture and air, causing it to rust. This is exactly what happens when you leave a bike out in the rain. Chemistry at work!
