What is chemical effect of electric current

Do you know what happens when electricity flows through a liquid or a solution? Some amount of chemical change takes place in that liquid or solution. This is what we call the chemical effects of electric current. Let us also study what electroplating is. To understand this concept in detail, explore the article below. •

ADVERTISEMENTS: Chemical Effects of Electric Current (explained with diagram)! We use electricity to run different things like fans, doorbells, heaters, bulbs, and so on. These devices make use of different effects of electric current such as the magnetic effect and the heating effect. Another often-used effect of electric current is its chemical effect. When electricity is passed through certain liquids, chemical changes take place. Some of these changes are useful to us. How do we pass electricity through a liquid? We put two electrodes in the liquid and apply a voltage across them. In a circuit, an electrode is a conductor that is in contact with a nonmetallic thing like a liquid or gas. The electrode connected to the positive terminal of a battery is called the anode, and the electrode connected to the negative terminal is called the cathode. ADVERTISEMENTS: Let us try to pass a current through different liquids. We will use an LED (light-emitting diode) to detect current. An LED needs less current than a bulb to work. So, it will glow even if the current flowing through the liquid is weak. An LED has two terminals—positive and negative. The positive terminal is longer. Connect it to the positive terminal of a 3-volt battery. Connect the negative terminals of the battery and the LED to wires attached to metal clips (or pins). The clips will act as electrodes. Take the test liquid in a small plastic or glass container. Dip the clips into the liquid. They should not touc...

Chemical Effects of Electric Current:When an electric current flows via a conducting solution, chemical reactions take place in the solution. This process can be described as the chemical effect of electric current. An excellent example of the chemical effect is when an electric current is passed through the solution of a metal salt; such as a solution of copper sulfate; copper metal gets deposited at the negative electrode as the metal is positively charged. Thus we can easily separate metal from its salt using this method. Chemical Effects of Electric Current: Overview Let us start with an experiment. Take a beaker, and fill it with tap water. Take a wire to connect a battery and bulb and form a circuit. Dip the two free ends of the wires into the beaker containing water or any liquid without touching each other, but also keep in mind that a large distance does not separate them. As shown in the figure below: Now, in the same set-up, replace tap water with salt water. Did you find any change in your observation? Yes, you will see that the bulb starts to shine brighter than in the previous set-up. Thus, we can conclude that some liquids are better conductors of electricity. Now replace the saltwater with distilled water and repeat the entire process, as shown in the figure below? Now, would you find any change in your observation? Yes, the bulb stops glowing! Thus, we can conclude that some liquids are insulators. To learn how some liquids can conduct and what happens whe...

The flow of an electric charge between two points i.e. point A & Point B is electric current. For better understanding Imagine water in a river carrying energy from one place to another. An electric current is capable of producing magnetic effects and chemical effects like electrochemical reactions. Electrons have an electric charge which causes resistors in the light bulbs and electric fires to heat up. Electrons also create magnetic fields in motors and generators. What is the Chemical Effect of Electric Current? The chemical reaction that takes place in a conducting solution after passing an electric current through it is called the chemical effect of electric current. Here are some good examples for better understanding the nature of the chemical effect of electric current. • Gas bubbles are formed at electrodes. • Metal deposits can be seen on electrodes • Change of texture or colour of the conducting solution. Conductor A material, substance or object which allows free flow of electric current is a good conductor. They conduct electricity because they allow electrons to flow within them on an atom level. Conductors are known for easy transmission of light and heat. Types of Conductor Conductors are mainly classified into two groups which are as follows, Good Conductors and Bad conductors. • Good Conductors Materials that allow electric current a free passage are good conductors of electricity. • Bad Conductors Materials that do not allow electric current free passage...

​Question 1 Define the term chemical effects? Question 2 What is electrolysis? Question 3 What is an acidified water? Question 4 Name one compound which is decomposed into hydrogen and oxygen by using chemical effects of electric current? Question 5 What should be done to decompose water into hydrogen and oxygen? Question 6 Acidified water is electrolysed by using carbon electrodes. What is produced at : Positive carbon electrode and negative carbon electrode? Question 7 Explain the chemical effect of electric current with the help of an example? Question 8 Explain why in the electrolysis of water, acidified water is used? Question 9 State some of the characteristics of chemical changes brought about by the chemical effect of electric current? Question 10 Name types of substances in which an electric current can produce a chemical effect? Chemical Effects Electric current can bring about chemical changes, so it said to have chemical effects. When electric current is passed through acidified water by using carbon electrodes, then a chemical reaction takes place to form hydrogen gas and Oxygen gas. A chemical compound water has been decomposed into two elements, hydrogen and oxygen, by the action of electric current. It is actually a chemical decomposition reaction caused by passing an electric current through acidified. The chemical decomposition produced by passing an electric current through a conducting liquid is called electrolysis. The water containing a little of acid...

Chemical effect of electricity: • A chemical reaction occurs when an electric current is transmitted through the solvent or solution. The consequences are known as the chemical effects of electric current. • Example: Whenever an electric current has been carried through a solution of a metal salt, including solutions of copper sulfate, metal however is accumulated at the negatively charged electrode even though the metal would be positively charged.
