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.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 falseD. If the assertion and reason both are false. |

Answer» Correct Answer - A Both assertion and reason are true and reason is the correct explanation of assertion. Anode (oxidation) for eq. `ZntoZn^(2+)+2e^(-)`, so Excess of electrons and hence negatively charged while cathode is positively charged. |
