Question

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

• A. In fig $(X)$, electrons flow from $Zn$ rod to $Cu$ rod hence current flows from $Cu$ to $Zn (E_{ext} < 1.1\,V)$
• B. In fig $(Y)$, electrons flow from $Cu$ to $Zn$ and current flows from $Zn$ to $Cu$ $(E_{ext} > 1.1 V)$
• 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.
