| Assertion: In an electrochemical cell anode and cathode are respectively negative and positive electrodes. |
| Reason: At anode oxidation takes place and at cathode reduction takes place. |
| Read the assertion and reason carefully to mark the correct option out of the options given below: |
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: A
Solution :
[a] Both assertion and reason are true and reason is the correct explanation of assertion. Anode (oxidation) for eq. \[Zn\xrightarrow{{}}Z{{n}^{2+}}+2{{e}^{-}}\], so Excess of electrons and hence negatively charged while cathode is positively charged.
