Question

Assertion :Zinc's non corrosive property is utilised in the process of galvanization. Reason: Galvanization refers to an electrodeposition process used to add a thin layer of another metal to an item made of steel, in order to prevent rusting.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

$\begin{array}{c}z\text{inc is a metal with a relatively Low}\text{galvanic potential and the corrosion rate}\\ \text{is low in most environments. since the}\text{surface of coating is quickly covered with}\\ \text{corrosion products, which subsequently}\text{protects against further corrosion.}\end{array}$

The reason that the galvanizing process uses zinc instead of other metals is that zinc oxidizes and experiences acid corrosion sacrificially to steel. It forms a protective layer of zinc that can't be corroded away.

Assertion and Reason are true and correct Explanations.
