Electroplating is one of the chemical effects of electric current. Electroplating is a chemical process using which a metal is coated with a layer of another desired metal.
What is the chemical effect of electric current?
The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of a gas may be formed on the electrodes. Deposits of metal may be seen on electrodes. Changes of colour of solutions may occur.
What is the chemical effect of electric current Class 8?
Chemical effect of the electric current: The passage of an electric current through a conducting solution causes chemical reaction. That may cause formation of bubbles of a gas on the electrodes, deposites of metal on electrodes, changes of colour of solutions etc.
What is mean by chemical effect of current?
The occurence of chemical reaction with the help of electricity(by passing electricity through the solution) is known as chemical effect of electric current. it is mainly used for decomposition of compounds or for electroplating any object.
What are the three chemical effects of electric current?
Chemical Effects of Electric Current
- Formation of gas bubbles at electrodes.
- Deposition of metals at electrodes.
- Changes in solution colour.
Is milk is a good conductor of electricity?
Milk is a good conductor of electricity because it contains water and lactic acids and other salts.
What are the four effects of electric current?
Name four different effects of electric current?
- Magnetic effect.
- Chemical effect.
- Heating effect.
- Electric shocks.
Which is a good conductor of electricity?
One of the most commonly used metals to conduct electricity is copper. … Copper is commonly used as an effective conductor in household appliances and in electrical equipment in general. Because of its low cost, most wires are copper-plated.
Do liquids conduct electricity Class 8?
Solution: Liquid conduct electricity because they have free ions as in acids, bases and salts being dissolved in water.
What is an electric circuit class 8?
The electric circuits are closed-loop or path which forms a network of electrical components, where electrons are able to flow. This path is made using electrical wires and is powered by a source, like a battery.
What are the applications of chemical effect of current?
Electroplating and electrolysis are the applications of chemical effect of electric current.
What does chemical effect mean?
When electric current is passed through a conducting solution, some chemical reaction takes place in the solution. This is called chemical effect of electric current. Change of colour of solution may occur. …
What are the chemical effects of electric current explain with example?
The resulting effects are called chemical effects of electric current. An example of the chemical effect is that When an electric current is passed through the solution of a metal salt, such as a solution of copper sulfate, metal gets deposited at the negative electrode because the metal is positively charged.
