Question
Given below are two figures of Daniell cell $$(X)$$ and $$(Y).$$ Study the figures and mark the incorrect statement from the following.
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 $$Zn$$ $$\left( {{E_{{\text{ext}}}} < 1.1\,V} \right).$$
B.
In fig. $$(Y),$$ electrons flow from $$Cu$$ to $$Zn$$ and current flows from $$Zn$$ to $$Cu\left( {{E_{{\text{ext}}}} > 1.1\,V} \right).$$
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 :
In fig. $$(Y),$$ $$Zn$$ is deposited at $$Cu$$ and $$Cu$$ is deposited at $$Zn.$$
Solution :
In fig. $$(Y),$$ zinc is deposited at the zinc electrode and copper dissolves at copper electrode.
In fig. $$(Y),$$ zinc is deposited at the zinc electrode and copper dissolves at copper electrode.
