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 is chemical effect of electricity 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 chemical effect of electricity give some examples of chemical effects?
The passage of an electric current through a conducting solution causes chemical reactions. The process in which chemical reaction takes place in a solution on passing electricity through it is because of chemical effect of current. For example, change in colour of solutions and electroplating.
What is effects of electricity?
The main effects are heating, chemical and magnetic effects. Effects of electric current. When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects.
What is meant by chemical effect?
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.
What do you meant by chemical effect of current?
The passage of an electric current through a conducting liquid causes chemical reactions
What is the example of chemical effect?
A very good 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.
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.
What are 3 effects of electric current?
Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.
What are 5 effects of electricity?
General effects of electric current
| Electric current (contact for 1s) | Effect |
|---|---|
| 50 to 150 mA | Extreme pain. Respiratory arrest. Muscles reactions. Possible Death. |
| 1 to 4.3 A | Fibrillation of the heart. Muscular contraction and nerve damage occur. Likely death. |
| 10 A | Cardiac arrest, severe burns. Death is probable |
What are the 4 effects of electricity?
There are four effects of electricity you can study on this line.
The ‘effects of electricity’ line
- magnetic effect.
- heating effect.
- chemical effect.
- electric shocks.
What are six harmful effects of electricity?
The possible consequences of an electric shock on the body
- A shock can cause muscle spasms.
- A shock can cause cardiac arrest.
- A shock can cause burns to tissues and organs.
- A shock can affect the nervous system.
- A shock can have other unexpected consequences.
Who discovered chemical effect of electric current?
It was Michael Faraday who studied extensively the passage of electricity through liquids. This process was called electrolysis, where the passage of electric current through a liquid causes chemical changes {in the liquid, as well as on the metal electrodes which are connected {anode and cathode} in the circuit.]
What is the magnetic effect of electricity Explain give an example of chemical effect of the electric current?
Electric current produces magnetic effect causing deflection of the magnetic needle of a compass. Therefore, when a tester is dipped in the solution, the needle shows deflection, being a good conductor of electricity.
What is the chemical effect of electric current on water?
William Nicholson, a British chemist demonstrated that bubbles of oxygen and hydrogen are formed when the electrodes are submerged in water and current is passed through the water.
What are the uses of chemical effect?
3: When current travels through water it gives them a medium for a chemical reaction. 4: It is used as a metal deposition during reaction. 5: Formation of bubbles is another use it. 6: It is used to change the color of the solution as well.
What are chemical effects of electric current list any two chemical effects of electric current?
Some of the chemical effects of electric current are as follows : Bubbles of gas may be formed at electrodes. Deposits of metal may be seen on electrodes. Change of colour of solution may occur.
What are the different types of effect produced by electricity?
The three effects of electric current are: 1. Heating effect 2. Magnetic effect 3. Chemical effect.
- Heating effect.
- Magnetic effect.
- Chemical effect. Was this answer helpful? Similar questions. In charging a battery of motor car, which of the following effect of electric current is used? Easy.
What are the effects of electricity Class 7?
Electric current has the following effect : (i) Electric current can give rise to heating and lighting. (ii) Electric current can convert a straight conductor into a temporary magnet.
What are the harmful effects of electricity?
Dangers of Electricity include a variety of hazards that include Electric Shock, Psychological Damage, Physical Burns, Neurological Damage and Ventricular fibrillation resulting in death. Any form of energy, when not properly controlled or harnessed, can result in serious danger to those who use it.
What are the negative effects of electricity?
