The questions given below consist of Statement I and Statement II. Use...
HgO Cathode ; Zn (anode)
Zn → Zn2+ + 2e–
Hg2+ + 2e– → Hg
Cell reaction
Zn + HgO → ZnO + Hg
No active species in cell reactions
⇒ no change in cell voltage.
Zn → Zn2+ + 2e–
Hg2+ + 2e– → Hg
Cell reaction
Zn + HgO → ZnO + Hg
No active species in cell reactions
⇒ no change in cell voltage.

The questions given below consist of Statement I and Statement II. Use...
Statement 1: The voltage of mercury cell remains constant for a long period of time.
Statement 2: It is because the net cell reaction does not involve active species.
Explanation:
The given statements are related to the voltage behavior of a mercury cell and the reason behind it.
Mercury Cell:
A mercury cell is a type of primary cell that uses a reaction between mercury and an electrolyte to generate electrical energy. It consists of a zinc anode, a mercury cathode, and an electrolyte containing potassium hydroxide.
Statement 1: The voltage of mercury cell remains constant for a long period of time.
The voltage of a mercury cell is indeed known to remain relatively constant over time. This is because the chemical reactions occurring within the cell are designed to maintain a stable voltage output. The voltage of a mercury cell is typically around 1.35 volts.
Statement 2: It is because the net cell reaction does not involve active species.
The net cell reaction refers to the overall chemical reaction that takes place in the cell to generate electricity. In the case of a mercury cell, the net cell reaction involves the oxidation of zinc at the anode and the reduction of mercury ions at the cathode.
The statement suggests that the reason for the constant voltage of the mercury cell is because the net cell reaction does not involve active species. This means that the reactants and products involved in the reaction are not highly reactive or prone to significant changes in concentration or potential.
Explanation of the Answer:
The correct answer is option A: Statement 1 is true, statement 2 is true, and statement 2 is the correct explanation for statement 1.
The voltage of a mercury cell remains constant because the net cell reaction does not involve highly reactive or active species. The reactants and products involved in the reaction are relatively stable, leading to a consistent voltage output over time. This is a characteristic feature of mercury cells.
It is important to note that the constant voltage of a mercury cell is desirable in many applications where a stable power source is required. However, mercury cells have been largely replaced by other types of batteries due to environmental concerns associated with the use of mercury.
Statement 2: It is because the net cell reaction does not involve active species.
