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=ItMnF

where, W = weight

I = current

t = time duration

M = Atomic mass

n = charge on ion.

F = Faraday's constant.
