Here are some key facts about the chemical effects of electric current: What happens? * When an electric current is passed through a conducting solution (called an electrolyte), it causes chemical reactions. * These reactions can lead to several observable effects: * Gas bubbles: Gases like hydrogen or oxygen may form at the electrodes (the points where the current enters and exits the solution). * Metal deposits: Metals can be deposited onto one of the electrodes. * Color changes: The color of the solution may change. Why does this happen? * Ionization: The electrolyte solution contains ions (charged particles). * Electrolysis: When the current flows, these ions are attracted to the electrodes and undergo chemical reactions. * At the cathode (negative electrode): Positive ions gain electrons and are reduced (e.g., metal ions form metal atoms). * At the anode (positive electrode): Negative ions lose electrons and are oxidized (e.g., water molecules may lose electrons to form oxygen gas). Applications * Electroplating: This process uses the chemical effects of electric current to coat metal objects with a thin layer of another metal. This can improve the appearance, corrosion resistance, or other properties of the object. * Electrolysis of water: This process uses electricity to split water into its constituent elements, hydrogen and oxygen. * Batteries: Batteries use chemical reactions to generate electricity. The reverse process, electrolysis, can be used to recharge some types of batteries. Key Points to Remember * The specific chemical reactions that occur depend on the type of electrolyte and the electrodes used. * The strength of the current and the duration of the current flow also affect the extent of the chemical reactions. * The chemical effects of electric current have many practical applications in various industries and technologies. Let me know if you would like to learn more about any specific aspect of the chemical effects of electric current.
24:12 As insulators don't have charged carriers so they resist the current flow and that's why they can't conduct electricity 56:15 In order to prevent rusting on iron, zinc is deposited. This process is called Galvanization.
As a senior, I remember those days when i used to study from Alok sir, his teaching style is just brilliant, I scored 98/100 in science after studying from him.
( 24:12 )Q1: Why don't electricity pass through insulator? ANS: Because insulators do not allow the flow of current as they do not have charged carriers to carry the energy source (electrons usually) which move freely. (56:10 ) Q2: What is galvanization? ANS: galvanization is the process where thin layer of zinc is coated on iron to prevent it from rusting this process is called electroplating.
The process of coating zinc on ion is known as galvanisation Thanku sir for explaining this chapter so easily i was thinking that this chapter was very hard but you make me to understand this chapter very easily ❤
The passage of current through a conducting material causes chemical reactions. The reactions are called electro chemical reactions and the resulting effects are called chemical effects of current

The electricity flows in the sea water because when salt is dissolved in this water the components of salt are broken into pieces (Na+,Cl-). Na+ and cl- are cation and anion respectively. These are the forms of ions. As we know that ions are charge carriers so we can conclude that sea water is a good conductor as it consists of charge carriers which make the flow of electricity easy.
1st question insulater se current paas kyu nhi hota..? Answer: kyuki usme charger carrier nhi hote.. 2nd question ka answer: iron pr zinc ki coating hoti hai Agr koi mistake hai to PlZZ correct kr dijiyega
The electrons in the insulators are bound to each other so tightly that there are no free electrons available for the movement. And that's how the electricity cannot be passed through them.
As insulators don't have charged carriers so they resist the current flow and that's why they can't conduct electricity In order to prevent rusting on iron, zinc is deposited. This process is called Galvanization.
