Question

Study the figure given below and answer the following questions :
Name the process depicted in the diagram.
Write the composition of the anode and the cathode.
Write the balanced chemical equation of the reaction taking place
in this case.
The reaction does not take place if a few drops of dilute sulphuric
acid are not added to water. Why?​

Answer 1

Answer:

1. electrolysis
2. oxygen and hydrogen
3. O2 + 2H2 gives rise to 2H2O
4. because it is an electrolyte solution........
5. hope it is helpful.......

Answer 2

Given that,

Oxygen = O₂

Hydrogen = H₂

Water =H₂O

(I). We need to name the process depicted in the diagram

The name of the process is electrolysis of water

(II). We need to write the composition of the anode and the cathode

Cathode = H₂

Anode = O₂

(III). We need to write the balanced chemical equation of the reaction taking place in this case

The balanced chemical equation is

$2H_{2}+O_{2}\Rightarrow 2H_{2}O$

(IV). The reaction does not take place if a few drops of dilute sulfuric acid are not added to water because it is an electrolyte solution.

Hence, This is required answers.
