Which of the following is observed when electric current is passed through a conducting solution?

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.

Which of the following observation can be observed when electric current is passed through an electrolyte in which two electrodes are present?

Textbook solution

Gas bubbles may be produced on the electrodes. Deposits of metal may be observed on electrodes. Change in the color of the solution may occur. The solution may get heated.

What effects are observed when electric current is passed through a conductor?

Answer: 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.

When electric current is passed through a conducting wire?

Thus, for a current carrying conductor, electric field inside the metal and the magnetic field outside the wire. Therefore, when an electric current is passed through a conducting wire along its length, the electric field exists inside the wire but parallel to it.

Which type of chemical effect of electric current is observed during electrolysis of water?

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.

When an electric current is passed through acidulated water?

Explanation: When an electric current is passed through acidulated water, it will produce electrolysis. During this process, water is decomposed into hydrogen and oxygen. The positive ions with some move to the cathode while the negative ions will also move to the anode.

What do you observe on passing electricity?

Observe the electrodes carefully. You will notice gas bubbles near the electrodes. … Oxygen bubbles formed on the electrode connected to the positive terminal of the battery and hydrogen bubbles formed on the other electrode. The passage of an electric current through a conducting solution causes chemical reactions.

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.

Which effects of electric current do you find?

Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect. Note:we have discussed briefly about the effects of current. You need to memorize the effects namely heating effect, magnetic effect and chemical effect.

When there is an electric current through a conducting wire along its length then the electric field must be?

Explanation:When there is an electric current through a conducting wire along its length, then an electric field must exist outside the wire but parallel to it.

What are the chemical effects observed when an electric current is passed through an electrolyte?

When an electrolyte such as copper sulphate is dissolved in water, it dissociates into positively and negatively charged ions called cation and anion. When electric current is passed through the solution, these ions start moving towards oppositely charged electrodes. This results into a chemical change in the solution.

What is chemical effect of electric current give two examples?

The most common examples of the chemical effect in electric currents are: Gold plating and chromium metal plating to prevent corrosion. 17. Name two metals which are usually electroplated on cheaper metals for making jewellery (or ornaments).

What is a chemical effect of current?

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.
