You asked: What are the chemical effects of electric current explain?

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 are the chemical effects 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 are the chemical effects of electric current explain with an 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.

What is meant by chemical effects of electricity?

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. …

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.

Which effect of current causes the bulb to glow?

Therefore, the effect of current responsible for the glow of the bulb in an electric circuit is the heating effect. So, the correct answer is “Option B”.

What is chemical effect?

Chemical effects pertain to aggressiveness of water and can be realized through: increase in solubility of rock, speeding up reactions, and introducing additional dissolution mechanisms (e.g., thermal mixing corrosion).

What are magnetic effects of electric current?

The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.

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.

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.

Is coconut water good conductor of electricity?

No. Coconut oil is a non polar liquid (when liquid) and does not have any free electrons which can move when you apply a potential (voltage) across it. Water is a polar solvent and contains free ions which can move depending on the potential applied (and hence conduct electricity).

Is petrol a good conductor of electricity?

question_answer Answers(1)

The typical value of the electrical conductivity of petrol is 25 pSm1 . This is very low for petrol to conduct. So petrol is a poor conductor of electricity.

Is vinegar a good conductor?

Vinegar is an aqueous solution of acetic acid and is produced by the fermentation process of ethanol or sugars. … Hence, we can say that vinegar is a good conductor of electricity.
