If both the assertion and reason are true but the reason is ont the correct explanation of assertionB. If both the assertion and reason are true but the reason is not the correct explanation of assertion.C. If the assertion is true but reason is false.D. If assertion is false but reason is rue
Answer» Correct Answer - a Zinc metal which has a more negative electrode potential tah iron will provide electorns in prefernce of the iron, and therfore corrodes first, Only when all the zinc has been oxidised then the iron start to rust .
