What physical changes may one observe upon passage of an electric current through a conducting solution?
Liquids which are good conductors:Some liquids too can conduct electricity, e.g. tap water, lemon juice, vinegar, salt solution, etc. Most of the liquids which conduct electricity are solutions of acid, base or salt.
Liquids which are bad conductors:Some liquids are bad conductors of electricity, e.g. distilled water, honey, milk, vegetable oil, etc.
Tap water conducts electricity because it contains various salts dissolved in it. Hence, it is advised not to touch an electric switch with wet hands.
Effects of Electric Current:
When electric current is passed through a conducing solution, some chemical reaction takes place in the solution. This is called chemical effect 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.
