When electric current is passed through water, it splits up into hydrogen & oxygen. This is called electrolysis of water.
What happens when an electric current passes through water?
When an electric current is passed through water, “Electrolysis of water” occurs, which is the decomposition of water (H2O) into hydrogen gas (H2) and oxygen (O2). Hydrogen gas forms at the cathode where the electrons enter the water and at the anode, oxygen is formed.
What happens when electric current is passed through water class 8?
Solution: When an electric current is passed through water, then water dissociates into hydrogen and oxygen. This is an example of the chemical effect of electric current.
What do you expect to happen when running electricity through pure water and ocean water?
Pure water doesn’t conduct electricity
In order for electricity to flow through a liquid, a movement of charge must take place through the liquid. Fully deionized water, in other words, absolutely “pure” water has no ions. Consequently, no charge flows through water, so pure water does not conduct electricity.
What are the effects of electric current?
The three effects of electric current are:
- Heating effect.
- Magnetic effect.
- Chemical effect. Was this answer helpful? Similar questions.
Does pure water conducts electricity explain?
Pure water does not conduct electricity. It does not contain salt and so it’s a poor conductor of electricity. To make pure water conducting, we can add salt to it.
When electric current is passed through acidulated water electrolysis of water takes place?
When electric current is passed through acidulated electrolysis of water takes place. Explanation: When an electric current is passed through acidulated water, it will produce electrolysis. During this process, water is decomposed into hydrogen and oxygen.
What are the 5 effects of electric current?
The main effects are heating, chemical and magnetic effects.
Effects of electric current
- Heating effect. When the flow of current is ‘resisted’ generally heat is produced. is is because the electrons while moving in the wire or resistor su er resistance. …
- Chemical effect. …
- Magnetic effect of Electricity.
What are the effects of electric current passing through a conductor?
An electric current is passing through a conductor which becomes hot after some time and produces heat. This is due to the conversion of some of the electrical energy that passes through the conductor, into heat energy. This effect of electric current is called the heating effect of current.
Which effect of electric current do you observe in the following figure?
heating effect. Whenever an electric current flows through a wire (conductor), a small amount of electrical energy is converted into heat energy. This is called the heating effect of electric current.
