In Class 8 Science, we learn that electric current can cause different effects: heating, magnetic, and chemical. The chemical effect of electric current occurs when electricity passes through a conducting liquid (electrolyte), causing chemical changes.
Chemical Effect: Chemical change caused by electricity passing through a liquid.
Electrolyte: A liquid that conducts electricity (e.g., salt solution, lemon juice).
Electrolysis: Chemical decomposition using electricity.
Electroplating: Coating one metal with another using electric current.
The passage of an electric current through a conducting solution causes chemical reactions. This phenomenon is called the chemical effect of electric current.
Common effects observed:
The process of breaking down a chemical compound (in liquid/aqueous state) by passing an electric current through it is called electrolysis.
The most common application of this effect is Electroplating. It is the process of depositing a layer of any desired metal on another material by means of electricity.
When an electric current passes through a conducting liquid, it causes chemical reactions (like gas bubbles or metal deposits). This is called the chemical effect of electric current.
Electroplating is the process of depositing a thin layer of a desired metal over another material using the chemical effect of electric current.
What is Planck's Quantum Theory?
Understand Max Planck's Quantum Theory of radiation. Learn how energy travels in small, discrete packets called 'Quanta' or 'Photons' rather than a continuous wave.
Point Charge — Definition, Electric Field and Potential
A point charge is an idealized model where all charge is concentrated at a single point. Learn Coulomb's law, electric field (E=kq/r²), and electric potential (V=kq/r) for Class 12 Physics.
