Question

When electric current passes through a bucket full of water, a lot of bubbling is observed. This suggests that the type of supply is
(A) AC
(B) DC
(C) Any of the above two
(D) None of the above

Answer 1

Hint : When the electric current passes through the bucket full of water, the process of electrolysis is formed and will find the current supply whether it is alternate current and the direct current.

Complete Step By Step Answer:
During the process of electrolysis, the breakdown of water molecules takes place and creates the hydrogen and the oxygen by means of an electric current which decomposes compounds other than water.
The electrolysis of water takes place when direct current is passed through the chemical compound.
Since, the water consists of water molecules which is represented by the formula ${H_2}O$
In the water molecules, a small fraction of the molecules exists in the form of ions or charged particles which are formed in water when water molecules break apart and form the positively charged hydrogen ions and negatively charged hydroxide ions.
The process can be expressed in the form of the chemical equation-
${H_2}0 \to {H^ + } + O{H^ - }$
The option B is the correct answer.

Note :
Always remember that the equipment used for the electrolysis of the compound which consists of the three parts such as the source of DC (direct current), two electrodes and an electrolyte. The most common arrangement consists of the battery with two poles which are attached with two strips of platinum metal electrodes.
