Chapter 18, Problem 18.42DP

Interpretation Introduction

Interpretation:

The anode system to protect the tank from corrosion should be designed.

Concept introduction:

• Corrosion is the chemical reaction occurred to reaction with atmospheric moisture and oxygen.
• Electroplating is a process of generating an electric current through the flow of electrons and ions through the separate path between metals.
• Electroplating is done in an electrochemical cell or corrosion cell to provide a protective or decorative coating against corrosion.

Weight of tank can be found by Faraday's equation,

  $W=\frac{ItM}{nF}$

where, W = weight

I = current

t = time duration

M = Atomic mass

n = charge on ion.

F = Faraday's constant.
