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 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 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 is chemical effect of electric current give two examples?
For example when an electric current is passed through acidified water then bubbles of oxygen and hydrogen gases are produced at two electrodes. This is a chemical effect of electric current. As solids conduct electricity, some of the liquids like acids, bases and salts also conduct electricity.
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.
How current is measured?
At its most basic, current = flow. An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called “electrical charge”) flowing past a point in a circuit over a given time. … A = amperes, for a large amount of current (1.000).
Do all liquids conduct electricity?
Electricity does not conduct through all liquids. Nonetheless, certain liquids are strong conductors of electricity while others are poor conductors. Water containing dissolved salts and minerals conducts electricity well, whereas pure water conducts electricity poorly.
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”. Note: Due to the moving electrons in the filament of the bulb, a magnetic field is also produced resulting in some magnetic effects.
Why is the current in the circuit weak?
Why is the current in the circuit weak? Liquids like water (mineral water, or water with impurities), acids, bases, salts, etc offers high resistance to current than metal conductors. So, after passing through conducting liquids the current in the circuit becomes weak.
What is the effect of current?
General effects of electric current
|Electric current (contact for 1s)||Effect|
|Below 1 mA||Not perceptible|
|1 mA||Threshold of feeling, tingling|
|5 mA||Slight shock. Not painful. Average individual can let go. Involuntary reaction can lead to indirect injuries|
|6-25 mA (women)||Painful shocks. Loss of muscle control|
Will the solution of sugar is distilled water conduct electricity?
The distilled water has no ions. … So, the distilled water is not able to conduct electricity. When the sugar is added to the distilled water then, the solution we get cannot conduct the electricity as the sugar solution is neither acidic nor basic.
