Question

Given below are two figures of Daniell cell (X) and (Y) Study the figures and mark the incorrect statement from the following.

• A. In Fig (X), electrons flow from Zn rod to Cu rod hence current flows from Cu to Zn $(E_{ext} < 1.1V)$
• B. In fig (Y), electrons flow from Cu to Zn and current flows from Zn to Cu $(E_{ext} < 1.1V)$
• C. In fig (X), Zn dissolves at anode and Cu deposits at cathode.
• D. In fig (Y), Zn is deposited at Cu and Cu is deposited at Zn.

Answer 1

Answer: (D)

In fig (Y), Zn is deposited at Cu and Cu is deposited at Zn.

Answer 2

In fig. (Y), Zinc is deposited at the zinc electrode and copper dissolves at copper electrode.
